Detailed Implementation

[0022] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0023] like Figures 1 to 6As shown, the stapler cartridge loading device in one embodiment of the present invention includes: an operating frame 1, a pair of moving blocks 103 and a loading mechanism 2.

[0024] like Figures 1 to 6 As shown, a clamping groove 101 is provided on one side of the operating frame 1. A pair of moving blocks 103 slide within the clamping groove 101, and a pair of grippers 104 are provided on each of the moving blocks 103. The nailing mechanism 2 is mounted on the operating frame 1 and includes: a nail storage chamber 201, a pair of locking components, multiple U-shaped grooves 211, multiple nail dispensing grooves 212, multiple push plates 213, and a cover plate 219. The nail storage chamber 201 slides on the operating frame 1, and a pair of locking components are respectively installed on both sides of the nail storage chamber 201 for fixing the nail storage chamber 201. Multiple U-shaped grooves 211 are equally spaced and carved into the nail storage chamber 201, and a U-shaped push plate 209 is slidably arranged in each U-shaped groove 211. A third spring 210 is installed between the end of the U-shaped push plate 209 away from the clamping groove 101 and the inner wall of the nail storage chamber 201. Multiple nail dispensing slots 212 are equally spaced and carved into one end of the nail storage chamber 201 near the clamping slot 101, and the nail dispensing slots 212 are connected to one end of the U-shaped slide 211 near the clamping slot 101. Multiple push plates 213 slide in the multiple nail dispensing slots 212 respectively, and control plates 214 are fixed to the top of the multiple push plates 213. The cover plate 219 rotates on the nail storage chamber 201, and multiple U-shaped pressure blocks 220 adapted to the U-shaped push plates 209 are fixed on the cover plate 219.

[0025] When using this device, the staple cartridge to be loaded is first placed into the clamping groove 101 and secured between the two pairs of grippers 104. Since the staple cartridge typically has six rows of slots, with each adjacent row staggered, the sliding distance of a pair of moving blocks 103 is equal to the offset distance between adjacent rows. After the staple cartridge is secured, the staple cartridge 201 is pushed towards the clamping groove 101. During this pushing process, the staple cartridge 201 is secured by a locking assembly. The locking assembly has multiple fixed points, each corresponding to a position of the staple slot 212 in each row of slots after the staple cartridge 201 has moved.

[0026] When the staple storage compartment 201 moves towards the clamping groove 101 and aligns the staple dispensing groove 212 with a row of staple slots in the staple compartment, the control plate 214 drives the push plate 213 to move downward. The push plate 213 slides downward in the staple dispensing groove 212, pushing the U-shaped staples in the groove downward so that they are inserted into the staple slots in the staple compartment. After the staples are loaded, the control plate 214 pulls the push plate 213 upward. After the push plate 213 moves away from the U-shaped slide 211, the elastic force of the third spring 210 pushes the U-shaped push plate 209 towards the clamping groove 101. The U-shaped push plate 209 pushes the U-shaped staples in the U-shaped slide 211 towards the staple dispensing groove 212, so that the next U-shaped staple is placed in the staple dispensing groove 212, ready for the next staple loading.

[0027] Additionally, the U-shaped nails need to be pre-installed in the U-shaped groove 211. When filling the U-shaped nails, first open the cover plate 219 from the nail storage chamber 201. The U-shaped push plate 209 drives the U-shaped pressure block 220 to rotate downwards and move out of the U-shaped push plate 209. Then push the U-shaped push plate 209 towards one side of the third spring 210. Then fill the U-shaped nails into the front end of the U-shaped push plate 209. Then release the U-shaped push plate 209. Through the elastic force of the third spring 210, the U-shaped push plate 209 pushes the U-shaped nails into the U-shaped groove 211. Then close the cover plate 219 on the nail storage chamber 201.

[0028] like Figures 1 to 6 As shown, two pairs of first sliding rods 102 are fixed on the bottom wall of the clamping groove 101, and a pair of moving blocks 103 slide on the two pairs of first sliding rods 102 respectively. The moving blocks 103 slide within the clamping groove 101 by sliding on the pair of first sliding rods 102. A connecting plate 105 is fixed between the pair of moving blocks 103, and a top plate 106 is fixed to one end of the connecting plate 105. The connecting plate 105 connects the pair of moving blocks 103 together, allowing them to slide together. The top plate 106 is used to press against one side of the staple cartridge to position it.

[0029] like Figures 1 to 6As shown, a pair of L-shaped support arms 202 are fixed to both sides of the staple storage compartment 201, and a pair of second slide rods 203 are fixed to both sides of the operating frame 1. The ends of the pair of L-shaped support arms 202 away from the staple storage compartment 201 slide on the pair of second slide rods 203 respectively. The staple storage compartment 201 slides on the operating frame 1 by sliding the pair of L-shaped support arms 202 on the pair of second slide rods 203 respectively. A second spring 208 is installed between the pair of L-shaped support arms 202 and the side wall of the operating frame 1, and the pair of second springs 208 are respectively sleeved on the pair of second slide rods 203. The elastic force of the pair of second springs 208 pushes the L-shaped support arms 202 in the opposite direction to the clamping groove 101, thereby causing the L-shaped support arms 202 to drive the staple storage compartment 201 to move in the opposite direction to the clamping groove 101, and then the locking assembly is used to fix the staple storage compartment 201.

[0030] like Figures 1 to 6 As shown, the locking assembly includes an L-shaped claw 204, multiple slots 206, and a spring groove 223. The L-shaped claw 204 rotates on an L-shaped support arm 202, and a locking head 205 is fixed to the bottom end of the L-shaped claw 204. Multiple slots 206 are carved into the top wall of the operating frame 1, and the locking head 205 is engaged in one of the slots 206. The spring groove 223 is carved into the L-shaped support arm 202, and a first spring 207 is installed between the bottom wall of the spring groove 223 and the L-shaped claw 204. When the nail storage chamber 201 is pushed towards the clamping groove 101, the locking head 205 slides outward in one of the slots 206, pushing the L-shaped claw 204 to rotate upward. When the locking head 205 moves to the next slot 206, the pulling force of the first spring 207 pulls the L-shaped claw 204 downward, causing the locking head 205 to engage in the slot 206. At this point, after the nail storage compartment 201 stops moving, the L-shaped support arm 202 is pushed in the opposite direction to the clamping groove 101 by the elastic force of the second spring 208, thereby causing the L-shaped support arm 202 to drive the nail storage compartment 201 to move in the opposite direction to the clamping groove 101. In addition, the nail storage compartment 201 is locked by the locking head 205 in the locking groove 206.

[0031] like Figures 1 to 6As shown, multiple third slide rods 215 are fixed on the staple storage compartment 201. A control plate 214 slides on these third slide rods 215. Multiple fourth springs 216 are installed between the control plate 214 and the staple storage compartment 201, each sleeved on one of the third slide rods 215. By sliding the control plate 214 on the third slide rods 215, the control plate 214 drives multiple push plates 213 to move vertically up and down. The elastic force of the fourth springs 216 pushes the control plate 214 upwards, causing it to move the push plates 213 upwards. Extension openings 218 are provided at the bottom of the staple storage compartment 201 at multiple staple dispensing slots 212. These extension openings 218 extend downwards to the top opening of the staple slot on the bottom of the staple compartment, allowing the U-shaped staples to directly enter the staple slot after exiting the staple dispensing slot 212.

[0032] like Figures 1 to 6 As shown, a knob lock 222 is installed between the staple storage compartment 201 and the cover plate 219, which is used to lock the cover plate 219 onto the staple storage compartment 201. A first handle 217 is fixed to one side of the control panel 214, and a second handle 221 is fixed to the top of the cover plate 219. The first handle 217 is used to push the control panel 214 downward, and the second handle 221 is used to rotate the cover plate 219 off the staple storage compartment 201 to open it.

[0033] Working principle: When using this device, first place the nail cartridge to be loaded into the clamping groove 101 and lock it between the two pairs of clamping claws 104, so that the head end of the nail cartridge rests on the top plate 106, thus completing the positioning of the nail cartridge. After the nail cartridge is fixed, push the nail storage cartridge 201 towards the clamping groove 101. When the nail storage cartridge 201 moves towards the clamping groove 101, the clamping head 205 slides outward in one of the clamping slots 206 and pushes the L-shaped clamping claw 204 to rotate upward. When the clamping head 205 moves to the next clamping slot 206, the pulling force of the first spring 207 pulls the L-shaped clamping claw 204 to rotate downward, causing the clamping head 205 to lock in the clamping slot 206. At this point, after the nail storage compartment 201 stops moving, the L-shaped support arm 202 is pushed in the opposite direction to the clamping groove 101 by the elastic force of the second spring 208, thereby causing the L-shaped support arm 202 to drive the nail storage compartment 201 to move in the opposite direction to the clamping groove 101. In addition, the nail storage compartment 201 is locked by the locking head 205 in the locking groove 206.

[0034] When the nail ejection slot 212 aligns with a row of nail slots in the nail magazine, the control plate 214 drives the push plate 213 to move downwards. The push plate 213 slides downwards in the nail ejection slot 212, pushing the U-shaped nails in the slots downwards so that they are inserted into the nail slots of the nail magazine. After the nailing is completed, the control plate 214 is pushed upwards by the force of the fourth spring 216, which in turn pulls the push plate 213 upwards. After the push plate 213 moves away from the U-shaped slide 211, the U-shaped push plate 209 is pushed towards the clamping groove 101 by the force of the third spring 210. The U-shaped push plate 209 pushes the U-shaped nails in the U-shaped slide 211 towards the nail ejection slot 212, so that the next U-shaped nail can be placed in the nail ejection slot 212, ready for the next nailing.
