Description

Technical Field

[0001] This utility model relates to the field of nailing machine technology, and more specifically to a safety device for nailing machines. Background Technology

[0002] Carton staplers are one of the finishing processes for cardboard boxes. Their principle is the same as that of ordinary staplers, except that carton staplers use toothed mortar as a backing plate. They are specifically designed for sealing cardboard boxes. This series of products has the advantages of being lightweight, easy to operate, wear-resistant, producing a flat and secure seal, and reducing labor intensity and improving work efficiency. They are widely used in various cardboard boxes and calcium plastic boxes that need to carry heavy items or are not easy to seal with adhesive tape.

[0003] For example, the existing carton nailing machine with publication number CN220742307U uses a rotary knob to drive a round rod to rotate. The rotation of the round rod drives a worm gear to rotate, which in turn drives a worm wheel. The rotation of the worm wheel supports the rotation of a support rod. The rotation of the support rod drives the support frame to rotate downwards. The downward rotation of the support frame drives the support block to rotate downwards. The downward rotation of the support block drives a ball bearing to rotate downwards. The downward rotation of the ball bearing drives the support plate to rotate downwards. Depending on the terrain, the rotation of the ball bearing drives the support plate to adjust its angle to fit the ground, thereby improving the nailing machine's grip and preventing it from moving, thus improving the stability of the nailing machine.

[0004] However, the existing technology described above still has the following problems in use: when nailing cardboard boxes with a nailing machine, the operator needs to manually place the cardboard box to be nailed under the nailing machine head, which can easily cause the operator's hand to be injured by the nailing machine head, posing a safety hazard. Based on this, the present invention provides a safety device for a nailing machine that can improve safety. Utility Model Content

[0024] Refer to the instruction manual appendix Figures 1-5This utility model provides a safety device for a box-nailing machine, including a base 1 and a box-nailing machine head 2. The box-nailing machine head 2 is fixed to the top of the base 1. A detachable pad 3 is fixed to the front end of the base 1. A safety feeding mechanism 4 is sleeved on the outer wall of the pad 3. The safety feeding mechanism 4 includes a sliding sleeve 41 sleeved on the outside of the pad 3. Two vertically distributed mounting plates 42 are fixed to the front end of the sliding sleeve 41. A pressure plate 43 is provided between the two mounting plates 42. An electric push rod 6 is fixedly inserted through the mounting plate 42 near the top of the sliding sleeve 41. The bottom end of the piston rod of the electric push rod 6 is fixed to the top of the pressure plate 43 and is used to drive the pressure plate 43 to rise and fall.

[0025] The bottom of the pad 3 is fixedly embedded with a first linear module 44, which is a linear transmission device. When the motor in the first linear module 44 drives the ball screw to rotate, the helical groove on the screw pushes the slide to move linearly. The bottom of the slide of the first linear module 44 is connected to the inner ring wall of the bottom of the slide sleeve 41, so as to drive the slide sleeve 41 to move automatically. A feeding plate 5 is provided below the pad 3, and a slide groove 7 is provided on the top of the pad 3. A slider 8 is fixedly provided on the inner ring wall of the top of the slide sleeve 41. The bottom of the slider 8 is located in the slide groove 7, and the slider 8 is fixed to the rear end of the mounting plate 42 near the slide groove 7. By using the slider 8 and the slide groove 7 to cooperate, the stability of the slide sleeve 41 when moving can be further improved.

[0026] An emergency stop switch 14 is fixedly embedded at the front end of the base 1. The emergency stop switch 14 can quickly cut off the power supply to the nailing machine head 2, thereby further improving the safety of the nailing machine. The top of the base 1 has multiple fixing holes 15, which are evenly distributed on the base 1. Multiple fixing holes 15 are used for installation. Bolts are passed through the fixing holes 15 to fix it to the table surface, thereby improving the stability of the entire device, keeping the entire device stable, and avoiding shaking of the device that affects the safety of use.

[0027] In actual use, the operator first places the cardboard board on the feeding plate 5 at the top of the base 1, then places both sides of the cardboard board on the pad 3, and uses the electric push rod 6 to extend and drive the pressure plate 43 to descend. The pressure plate 43 and the mounting plate 42 work together to clamp the rear end of the cardboard board. Then, the nut block on the first linear module 44 drives the sliding sleeve 41 to move backward, which can drive the cardboard board to move backward automatically. During the movement, the cardboard board is nailed by the nailing machine head 2, thus completing the automatic connection of the cardboard board. After nailing, the sliding sleeve 41 moves forward again to push the cardboard board off the pad 3, which facilitates quick unloading. The movable sliding sleeve 41 automatically drives the cardboard board to move back and forth, avoiding the operator's hands from reaching under the nailing machine head 2 and being injured, thus improving the safety of the nailing machine.

[0028] Refer to the instruction manual appendix Figure 1 and Figure 2The front surface of the base 1 has a slot 9 that is compatible with the pad 3.

[0030] The base 1 has two fixed second linear modules 13 on its top sides. The working principle of the second linear module 13 is the same as that of the first linear module 44, which will not be described in detail here. The slides of the two second linear modules 13 are fixed to the two side baffles 11 respectively. The feeding plate 5 is moved up and down synchronously by the two second linear modules 13, so as to facilitate automatic adjustment of the height of the feeding plate 5 and assist the staff to quickly load materials.

[0031] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
