DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] The core of the present invention is to provide a screw gun device capable of automatically feeding nails, which can effectively improve the nailing efficiency of the screw gun.

[0033] Please refer to Figures 1 to 3 ,in, Figure 1 An exploded schematic diagram of a screw gun device capable of automatically feeding nails provided by the present invention; Figure 2 This is an exploded schematic diagram of the fixing seat; Figure 3 This is an exploded diagram of the drive seat.

[0034] The present specific embodiment provides a screw gun device capable of automatically feeding nails, comprising: a left machine cover 1, a right machine cover 2 for forming a chamber with the left machine cover 1, a fixing seat 3 for clamping with a screwdriver, a length adjustment frame 4 that can move forward and backward relative to the axial direction of the fixing seat 3, a driving seat 5 connected to the length adjustment frame 4, and a compression spring 6. The fixing seat 3 is arranged at the rear end of the chamber, the driving seat 5 is arranged at the front end of the chamber, the fixing seat 3 and the driving seat 5 are both in contact with the elastic end of the compression spring 6, and the length adjustment frame 4 is a U-shaped structure, and the left and right sides of the U-shaped structure are divided into The U-shaped structure is respectively connected with the left and right sides of the driving seat 5, and the bottom edge of the U-shaped structure is provided with a nailing hole 7; the driving seat 5 is provided with a mounting groove 8 for passing the screw conveyor belt, and a gap is left between the bottom edge and the mounting groove 8. The left machine cover 1 is provided with a sliding guide groove. When the length adjustment frame 4 moves backward, the driving member 54 of the driving seat 5 can rotate in the sliding guide groove, and the driving member 54 can drive the screw conveyor belt to move so that the screws on the screw conveyor belt are aligned with the nailing holes 7. The screwdriver bit can pass through the fixed seat 3, the compression spring 6 and the driving seat 5 in sequence to drive the screw to rotate.

[0035] It should be noted that the driving member 54 can drive the screw conveyor belt to move so that the screws on the screw conveyor belt are aligned with the nail holes 7, which means that during the rotation of the driving member 54, the screw conveyor belt can be moved so that the screws on the screw conveyor belt are moved to a position aligned with the nail holes 7, and then, the bit of the screwdriver is passed through the fixing seat 3, the compression spring 6 and the driving seat 5, and abutted against the end of the screw. After the screwdriver is running, the bit can drive the screw to rotate, so that the screw at the nail hole 7 completes the nailing and tightening operation.

[0036] In actual use, the shape, structure, size, position, material, etc. of the left machine cover 1, the right machine cover 2, the fixing seat 3, the length adjustment frame 4, the driving seat 5 and the compression spring 6 can be determined according to actual conditions and actual needs.

[0037] When using the screw gun device capable of automatically feeding nails provided by the present invention, the fixing seat 3, the driving seat 5, the compression spring 6, the length adjustment frame 4 and other components can be installed in the chamber, the screws can be installed on the screw conveyor belt at equal intervals, and the screw conveyor belt can be passed through the installation slot 8 of the driving seat 5. After that, the front end of the screwdriver is clamped with the fixing seat 3, and the screwdriver bit can pass through the fixing seat 3, the compression spring 6 and the driving seat 5 in sequence, so that the screwdriver bit is abutted against the screw, so as to drive the screw to rotate for nailing operation.

[0038] When nailing is required, the length adjustment frame 4 can be moved backwards, and the length adjustment frame 4 can drive the driving seat 5 to move backwards when it moves backwards. When the driving seat 5 moves backwards, the driving member 54 can rotate in the sliding guide groove. The driving member 54 can drive the screw conveyor belt to move during the rotation process, so that the screws on the screw conveyor belt are aligned with the nailing holes 7. At the same time, the screw head can be abutted against the screw, thereby driving the screw to rotate for nailing. After completing the nailing operation of the screw, the length adjustment frame 4 can be reset under the action of the compression spring 6 to facilitate the next screw movement and rotation nailing operation. The device can perform continuous nailing operations on multiple screws on the screw conveyor belt in sequence to improve the efficiency of the nailing operation.

[0039] In summary, the screw gun device capable of automatically feeding nails provided by the present invention can effectively improve the nailing efficiency of the screw gun.

[0040] On the basis of the above embodiment, preferably, the fixing seat 3 includes a connecting sleeve 31 for clamping with the screwdriver, a locking knob 32 for rotationally locking or unlocking the connecting sleeve 31 and the screwdriver, a fixing sleeve 33, a depth adjustment knob 34 and a depth positioning sleeve 35; the front end of the connecting sleeve 31 is connected to the rear end of the fixing sleeve 33, and a locking knob 32 is sandwiched between the rear end of the connecting sleeve 31 and the rear end of the fixing sleeve 33, the depth positioning sleeve 35 is sleeved on the inner periphery of the front end of the fixing sleeve 33, and the depth adjustment knob 34 is sleeved on the outer periphery of the front end of the fixing sleeve 33. When the depth adjustment knob 34 is rotated clockwise or counterclockwise, the depth positioning sleeve 35 can move forward and backward.

[0041] It should be noted that the depth adjustment knob 34 and the depth positioning sleeve 35 are arranged in a screw-nut type, so the depth positioning sleeve 35 can be driven to move forward and backward when the depth adjustment knob 34 is rotated. After the depth positioning sleeve 35 moves forward and backward, the distance between the depth positioning sleeve 35 and the length adjustment frame 4 will change. The size of the screwdriver bit is fixed, and the distance between the depth positioning sleeve 35 and the length adjustment frame 4 plus the nailing depth of the screw is equal to the size of the screwdriver bit. Therefore, the depth positioning sleeve 35 moves backward to increase the nailing depth of the screw, and the depth positioning sleeve 35 moves forward to reduce the nailing depth of the screw. By adjusting the depth adjustment knob 34, the nailing depth adjustment operation can be achieved.

[0042] Preferably, the connecting sleeve 31 is provided with at least two tapered holes 37 distributed radially, a steel ball 38 is provided in the tapered hole 37, the end of the tapered hole 37 close to the outside is the first port, the end of the tapered hole 37 close to the inside is the second port, the diameter of the first port is larger than the diameter of the steel ball 38, the diameter of the steel ball 38 is larger than the diameter of the second port, and the locking knob 32 is provided with a groove 39 corresponding to the first port to accommodate the steel ball 38.

[0043] It should be noted that when it is necessary to realize the quick unlocking function of the screwdriver and the connecting sleeve 31, the locking knob 32 can be rotated so that the groove 39 of the locking knob 32 is rotated to the first port, and the steel ball 38 will move in the tapered hole 37 from the second port to the first port. Since the first port and the groove 39 can completely accommodate the steel ball 38, the contact between the steel ball 38 and the front end of the screwdriver is avoided. At this time, the screwdriver can move freely in the connecting sleeve 31 to realize the unlocking operation of the screwdriver and the connecting sleeve 31.

[0044] When it is necessary to realize the quick locking function of the screwdriver and the connecting sleeve 31, the locking knob 32 can be rotated in the opposite direction to separate the groove 39 of the locking knob 32 from the first port. The side wall of the locking knob 32 will push the steel ball 38 to move in the tapered hole 37, so that the steel ball 38 moves from the first port to the second port. Since the diameter of the second port is smaller than the diameter of the steel ball 38, the steel ball 38 will be partially exposed at the second port. This can prevent the steel ball 38 from falling off and can also abut the front end of the screwdriver through the exposed part of the steel ball 38, thereby effectively clamping and fixing the screwdriver, thereby realizing the clamping and locking effect of the screwdriver and the connecting sleeve 31.

[0045] Preferably, the front end of the depth positioning sleeve 35 is fitted with a depth positioning pad 36. The depth positioning pad 36 can be set as a wear-resistant material to avoid friction damage to the depth positioning sleeve 35 during use, effectively improving the service life of the depth positioning sleeve 35.

[0046] In actual use, the shape, structure, size, material, position, etc. of the connecting sleeve 31, the locking knob 32, the fixing sleeve 33, the depth adjustment knob 34, the depth positioning pad 36 and the depth positioning sleeve 35 can be determined according to actual conditions and actual needs.

[0047] On the basis of the above embodiments, preferably, the drive seat 5 includes a left box body 51, a right box body 52 that cooperates with the left box body 51 to form a cavity, and a length adjustment button 53. The driving member 54 is arranged in the cavity and can pass through the left box body 51 to contact the sliding guide groove. A positioning buckle 55 is provided at the bottom of the length adjustment button 53. A positioning card groove 56 is axially provided on the right side of the length adjustment frame 4. The right box body 52 is provided with a through hole for passing the positioning buckle 55, and the positioning buckle 55 is matched with the positioning card groove 56; the length adjustment button 53 can be raised and lowered at the top of the cavity. When the length adjustment button 53 is pressed down, the positioning buckle 55 is disengaged from the positioning card groove 56. When the length adjustment button 53 moves up, the positioning buckle 55 is engaged with the positioning card groove 56.

[0048] It should be noted that, since the length adjustment button 53 can move up and down within a certain range of the cavity, when the length adjustment button 53 is pressed downward, the length adjustment button 53 can drive the positioning buckle 55 to descend, so that the positioning buckle 55 is disengaged from the positioning slot 56, thereby unlocking the length adjustment frame 4, so that the length adjustment frame 4 can slide forward and backward, thereby sliding the length adjustment frame 4 to a desired position according to the actual nailing length, and then moving the length adjustment button 53 upward again, so that the positioning buckle 55 falls into the positioning slot 56 of the length adjustment frame 4 to lock the length adjustment frame 4. The process of moving the length adjustment frame 4 forward and backward allows screws of different lengths to be inserted into the nailing hole 7 for nailing.

[0049] In actual use, the shape, structure, size, material, position, etc. of the left box body 51, the right box body 52, the length adjustment button 53, the positioning buckle 55 and the positioning slot 56 can be determined according to actual conditions and actual needs.

[0050] Preferably, the driving member 54 includes a central shaft 541, a tape feed wheel 542, a driving disk 543, a clutch claw 544, a roller 545 and a roller shaft 546. The driving disk 543 and the tape feed wheel 542 are both sleeved on the central shaft 541, and the two ends of the central shaft 541 are respectively arranged on the left box body 51 and the right box body 52; the left end surface of the driving disk 543 is provided with a mounting hole, and the roller shaft 546 is sleeved with the roller 545 and installed in the mounting hole, and the other side of the roller shaft 546 is provided with an open retaining ring so that the roller shaft 546 is axially fixed on the driving disk 543, and the roller 545 can extend out of the left box body 51 and contact the sliding guide groove. When the length adjustment frame 4 moves backward, the roller 545 moves from high to low in the sliding guide groove, so that the driving disk 5 43 rotates; a clutch claw 544, a fixed pin 547 for positioning the clutch claw 544 and a tension spring 548 for pulling the clutch claw 544 are provided on the right end face of the driving disk 543, and small teeth are provided on the left and right sides of the tape feeding wheel 542, and the small teeth are engaged with the left and right notches on the screw conveyor belt. Each rotation of the tape feeding wheel 542 can drive the screw conveyor belt to move one grid; a countersunk hole is provided on the left end face of the tape feeding wheel 542, and a first ratchet tooth is provided at a position corresponding to the small tooth in the circumference of the countersunk hole. When the driving disk 543 rotates counterclockwise, the clutch claw 544 contacts the front side of the first ratchet tooth to drive the tape feeding wheel 542 to rotate. When the driving disk 543 rotates clockwise, the clutch claw 544 contacts the back side of the first ratchet tooth and can skip the tape feeding wheel 542.

[0051] Preferably, a circular convex end is provided on the right side end face of the tape feed wheel 542, and a second ratchet is provided at a position corresponding to the small tooth in the circumferential direction of the circular convex end. The right box body 52 is provided with a stop spring 549. When the tape feed wheel 542 rotates counterclockwise, the stop spring 549 contacts the back side of the second ratchet and does not hinder the rotation of the tape feed wheel 542. When the tape feed wheel 542 rotates clockwise, the stop spring 549 contacts the front side of the second ratchet to prevent the tape feed wheel 542 from rotating.

[0052] It should be noted that when performing the nailing operation, the length adjustment frame 4 can be pressed backward, and the length adjustment frame 4 can drive the driving member 54 to move backward together. At this time, the roller 545 on the left side of the driving disk 543 can move from high to low in the sliding guide groove, so that the driving disk 543 rotates counterclockwise, and the clutch claw 544 on the right side of the driving disk 543 will stop at the front side of the first ratchet tooth at the countersunk hole to drive the belt feeding wheel 542 to rotate together. When the belt feeding wheel 542 rotates, the small teeth of the belt feeding wheel 542 can drive the screw conveyor belt to move. Each rotation of the belt feeding wheel 542 can drive the screw conveyor belt to move one grid to realize the belt feeding action, so that the screw is inserted into the nailing hole 7, and then the nailing operation is performed.

[0053] When a nailing operation is completed, the external force can be released, and the length adjustment frame 4 and the driving member 54 can automatically reset under the action of the compression spring 6. At this time, the roller 545 of the driving disk 543 can move from low to high in the sliding guide groove, so that the driving disk 543 rotates clockwise. When the driving disk 543 rotates clockwise, it will not drive the tape feeding wheel 542 to rotate. At this time, the stopping spring 549 on the right box body 52 will stop on the front side of the second ratchet tooth of the tape feeding wheel 542, preventing the tape feeding wheel 542 from rotating, and finally making the tape feeding wheel 542 stop at the initial position after resetting, ensuring that the tape feeding wheel 542 is accurately reset.

[0054] Preferably, the belt feeding wheel 542 is evenly provided with 8 small teeth along the circumference, the counterbore is evenly provided with 8 first ratchet teeth along the circumference, and the circular protruding end is evenly provided with 8 second ratchet teeth along the circumference, so as to ensure that each rotation of the belt feeding wheel 542 can drive the screw conveyor belt to move one grid to realize the belt feeding operation. This can ensure the transmission effect of the device and facilitate the processing and manufacturing of the device.

[0055] In actual use, the shape, structure, size, material, position, etc. of the central shaft 541, the tape feed wheel 542, the driving disk 543, the clutch claw 544, the roller 545 and the roller shaft 546 can be determined according to actual conditions and actual needs.

[0056] Based on the above embodiment, preferably, the positioning slot 56 is marked with size scales along the axial direction. Therefore, the length adjustment frame 4 can be slid to the corresponding scale position according to the actual nailing length, ensuring that the device is suitable for nailing screws of different lengths.

[0057] Preferably, the left box body 51 and the right box body 52 are buckled together to form an adjustment slot 57, and the adjustment slot 57 is used to clamp and fix the length adjustment button 53. A reset spring 58 is provided at the bottom of the length adjustment button 53, and the reset spring 58 is provided in the cavity. Therefore, after pressing the length adjustment button 53 downward and then removing the downward pressure, the length adjustment button 53 can move upward and reset under the action of the reset spring 58, and finally get stuck in the position of the adjustment slot 57, without the operator having to pull the length adjustment button 53 upward.

[0058] It should also be noted that the device can be used in conjunction with a screw conveyor belt equipped with multiple screws to achieve continuous nailing operations. Moreover, the device can adjust the length of the screws and the depth of nailing, effectively improving the application range of the device.

[0059] It should be noted that the first ratchet and the second ratchet, the first port and the second port mentioned in the present application document, wherein the first and the second are only for distinguishing the different positions, have no order of precedence.

[0060] In addition, it should be noted that the directions or positional relationships indicated by "left and right", "front and back" and so on in the present application are based on the directions or positional relationships shown in the drawings and are only for the purpose of simplifying the description and facilitating understanding.
