Detailed implementation mode

[0017] The following specifically introduces the present utility model in conjunction with the attached drawings and specific embodiments.

[0018] Embodiment: A U-shaped nail stapling machine, as Figure 1 -

[0019] Figure 4 shown, includes a base 1, a mounting housing 2, a mounting plate 3, a shaping component and a pushing component. The rear side of the top of the base 1 is fixedly connected with a mounting housing 2. The mounting housing 2 is a square housing, and an opening is formed in the upper part of its front panel. A mounting plate 3 is welded and fixed on the left panel of the mounting housing 2 near the opening. A shaping component for shaping the U-shaped nail is arranged on the mounting plate 3, and a pushing component for pushing the U-shaped nail into the shaping component is arranged inside the mounting housing 2.

[0020] As Figure 1 、 Figure 2 and Figure 3 shown, the shaping component includes a guide rail 4, a forming block 42, a mounting sleeve 43, a guide rod 44 and a fastening screw 45. The guide rail 4 is detachably arranged on the mounting plate 3. A nail groove 41 for positioning the U-shaped nail is formed in the middle of the guide rail 4. The forming block 42 is fixed on the front side of the guide rail 4 by bolts. The mounting sleeve 43 is welded and fixed on the front side of the top of the mounting housing 2. A guide rod 44 is arranged in the mounting sleeve 43. The bottom of the guide rod 44 is attached and aligned with the nail groove 41 to ensure that the U-shaped nail can smoothly fall into the nail groove 41. A fastening screw 45 for fixing the guide rod 44 is threadedly connected to the mounting sleeve 43.

[0021] As Figure 1 、 Figure 2 and Figure 3As shown in the figure, the pushing component includes a rotating shaft 51, a crank handle 501, a slide rail 52, an L-shaped slider 53, a rotating plate 54, a pressing block 56, a fixing plate 57, a return spring 58 and a thruster 59. The front side of the lower part of the installation housing 2 is rotatably connected to the rotating shaft 51. The right end of the rotating shaft 51 is fixed with the crank handle 501 by bolts. Two slide rails 52 are welded and fixed at intervals up and down on the opposite side walls of the left and right side panels of the installation housing 2. An L-shaped slider 53 is slidably arranged on each adjacent two slide rails 52. A fixing plate 57 is welded and fixed between the front sides of the two L-shaped sliders 53. A return spring 58 is connected between the fixing plate 57 and the rear panel of the installation housing 2 to realize the automatic reset function. A thruster 59 for pushing the U-shaped nails is fixed to the front side of the fixing plate 57 by bolts. A rotating plate 54 is welded and fixed in the middle of the rotating shaft 51. On the side of the rotating plate 54 far from the rotating shaft 51, pressing blocks 56 are symmetrically welded and fixed on the left and right. Slide grooves 55 are formed on the opposite side walls of the two L-shaped sliders 53. The two pressing blocks 56 can slide in the adjacent slide grooves 55 respectively, so as to drive the L-shaped sliders 53 and the fixing plate 57 to move back and forth.

[0022] First of all, the operator selects a matching guide rail 4 and a guide rod 44 according to the model of the U-shaped nails to be used, and firmly installs the guide rail 4 on the mounting plate 3 by bolts. Since the mounting plate 3 is arranged outside the installation housing 2, the guide rail 4 can be quickly replaced and installed. Subsequently, loosen the fastening screw 45, insert the guide rod 44 into the installation sleeve 43, ensure that the bottom of the guide rod 44 is accurately aligned and fitted with the preset nail groove 41 on the guide rail 4, and then tighten the fastening screw 45 to fix the guide rod 44. In this way, the replacement of the guide rail 4 and the guide rod 44 becomes fast and convenient to adapt to different models of U-shaped nails. After installing the guide rail 4 and the guide rod 44, the operator places the U-shaped nails in the guide rod 4. Under the action of its own gravity, the U-shaped nails naturally fall into the nail groove 41 on the guide rail 4. Next, the operator rotates the crank handle 501 forward. The crank handle 501 drives the rotating plate 54 to rotate clockwise through the rotating shaft 51. In this process, the pressing block 56 on the rotating plate 54 interacts with the slide groove 55 on the L-shaped slider 53, pushing the two L-shaped sliders 53 to slide forward smoothly along the slide rail 52. As the L-shaped slider 53 moves, the fixing plate 57 and the thruster 59 on its front side also move forward. At this time, the return spring 58 is stretched. When the thruster 59 moves forward, it separates and pushes forward the U-shaped nails located in the nail groove 41, so that the U-shaped nails slide along the guide rail 4 and finally enter the forming block 42. Under the action of the forming block 42, the U-shaped nails are closed inward, thus completing the sealing operation of the packaging bag. After the sealing is completed, the operator releases the crank handle 501. Under the elastic force of the return spring 58, the fixing plate 57 automatically moves backward and resets, thereby driving the L-shaped slider 53, the rotating plate 54 and the crank handle 501 to return to their initial positions in sequence, preparing for the next sealing operation.

[0023] As shown Figure 4 shown, it further includes a placement groove body 6 and a placement plate 61. The placement groove body 6 is fixedly welded to the left side of the middle part of the installation housing 2, and the placement plate 61 is fixedly welded to the left side of the lower part of the installation housing 2.

[0024] By setting the placement groove body 6 and the placement plate 61, the operator can neatly place guide rods 44 of different models in the placement groove body 6, and the placement plate 61 supports the bottoms of these guide rods. This not only facilitates the centralized storage of these guide rods 44, but also helps to quickly find the required model of guide rod 44, improving work efficiency.

[0025] As shown Figure 1 shown, it further includes a pressing nail block 7, and the pressing nail block 7 is slidably arranged in the guide rod 44.

[0026] By setting the pressing nail block 7, a stable downward pressure can be applied to the U-shaped nails inside the guide rod 44, ensuring that the U-shaped nails remain stable in the guide rod 44, preventing them from shaking or jamming, so that they can smoothly and accurately fall into the nail grooves 41 on the guide rail 4.

[0027] As shown Figure 4 shown, it further includes a mounting seat 81, a guiding door 82 and a push-pull spring 83. The mounting seat 81 is fixedly connected to the front side of the lower part of the mounting sleeve 43. The guiding door 82 is rotatably connected to the mounting seat 81 through a rotating shaft, and a push-pull spring 83 is connected between the guiding door 82 and the fixing plate 57.

[0028] When performing the bag-tying operation on the packaging bag, the fixing plate 57 moves forward. First, it pushes the push-pull spring 83, and then the push-pull spring 83 pushes the guiding door 82 to rotate around the rotating shaft to the bag-tying position of the packaging bag. The function of the guiding door 82 is to gather the scattered part of the bag mouth for subsequent bag-tying operation. Due to the characteristic of continuous compression deformation of the push-pull spring 83, when the fixing plate 57 continues to push the pusher 59 forward, the push-pull spring 83 can continuously apply a thrust to ensure that the guiding door 82 remains in the current state of gathering the bag mouth. When the fixing plate 57 moves backward and resets, the length of the push-pull spring 83 gradually recovers, thereby pulling the guiding door 82 back to the initial position to prepare for the bag-tying operation of the next packaging bag.

[0029] The above has introduced this application in detail. Specific examples are used in this article to elaborate on the principle and implementation manner of this application. The description of the above embodiments is only used to help understand the method and its core idea of this application; at the same time, for those of ordinary skill in the art, according to the idea of this application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to this application.
