Technical Field

[0001] The utility model relates to the technical field of earplug packaging, in particular to a pin inserting device for an earplug box. Background Art

[0002] After earplugs are processed and produced, they need to be packaged in pairs in boxes or bags for convenient storage and use. In the production of earplug boxes, in order to enable the earplug boxes to be repeatedly opened during use, the cover body and the box body of the earplug box are connected by a pin hinge. During the installation of the pin, due to the small size of the earplug box, the pin is short and thin, and it is difficult to manually insert the pin into the target position, and the efficiency is low. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a pin inserting device for an earplug box, which can quickly install the pin in the earplug box.

[0004] To achieve the above-mentioned utility model purpose, the utility model provides a pin inserting device for an earplug box, which includes a workbench, a propulsion cylinder, a push pin, and a limiting member;

[0005] The workbench is provided with a material placing groove and a fixing groove, and the limiting member is fixed in the fixing groove;

[0006] The limiting member is located between the propulsion cylinder and the material placing groove, and the push pin is connected to the propulsion cylinder;

[0007] The limiting member includes a limiting block and a base, the limiting block is provided with a limiting channel, the limiting channel is coaxially arranged with the push pin, and the limiting block is fixed on the workbench through the base.

[0023] The following further details the specific embodiments of the utility model with reference to the accompanying drawings.

[0024] As Figures 1-3 shown, a pin insertion device of an earplug box of the utility model includes a workbench 1, a pushing cylinder 2, a push pin 3, and a limiting member 4;

[0025] The workbench 1 is provided with a material placing groove 11 and a fixing groove 13. The material placing groove 11 is used for placing the earplug box 5, and the limiting member 4 is fixed in the fixing groove 13. The four corners of the material placing groove 11 are provided with material taking grooves 12. The earplug box 5 is stuck in the material placing groove 11 to position the box body in the groove, preventing the box body from shifting when installing the pin shaft 52 and affecting the insertion of the pin shaft 52. The material taking groove 12 facilitates the removal of the earplug box 5 in the groove, avoiding scratching the surface of the box body when removing the box body after the outer wall of the box is closely attached to the inner wall of the material placing groove 11.

[0026] The limiting member 4 is located between the pushing cylinder 2 and the material placing groove 11, and the push pin 3 is connected to the pushing cylinder 2.

[0027] The limiting member 4 includes a limiting block 41 and a base 53. The limiting block 41 is provided with a limiting channel 44, and the limiting channel 44 is coaxially arranged with the push pin 3. The limiting block 41 is fixed on the workbench 1 through the base 53.

[0028] The fixing groove 13 is provided with a fastening hole 14, and the fastener 42 detachably fixes the base 53 on the workbench 1 through the fastening hole 14, facilitating the replacement of the limiting member 4. The push pin 3 moves back and forth in the limiting channel 44 for a long time, and the limiting channel 44 will be worn and widened, affecting the limiting effect on the push pin 3.

[0029] The limiting block 41 is provided with an opening groove 45, and the opening groove 45 is communicated with the limiting channel 44. The movement of the push pin 3 in the limiting channel 44 can be observed through the opening groove 45, facilitating debugging and maintenance.

[0030] Preferably, the number of the limiting members 4 and the pushing cylinders 2 is two each. The two limiting members 4 are located on both sides of the material placing groove 11 and between the two pushing cylinders 2. Since the specifications and styles of the earplug boxes 5 are different, the insertion directions of the pin shafts 52 will be different accordingly. The pushing cylinders 2 and the push rods 3 are arranged on both sides of the earplug box 5. According to the installation requirements of the pin shaft 52, one of the pushing cylinders 2 on one side of the earplug box 5 is selected to control the corresponding push rod 3 to push the pin shaft 52.

[0031] The workbench 1 is provided with two control buttons 6, and the two control buttons 6 are respectively connected to the solenoid valves of the corresponding pushing cylinders 2. The working states of the two pushing cylinders 2 are controlled by selecting and pressing the control buttons 6.

[0032] The connection end of the push pin 3 and the pushing cylinder 2 is provided with a reinforcing rod 31. Since the push pin 3 plays a role in pushing the pin shaft 52, the push pin 3 is long and thin in diameter. The reinforcing rod 31 can play a role in strengthening the push pin 3, preventing the push pin 3 from bending downward due to gravity and affecting the docking of the push pin 3 and the pin shaft 52.

[0033] The workbench 1 is provided with a fixing plate 21. The fixing plate 21 is provided with a limiting hole 22. The pushing cylinder 2 is fixed on the fixing plate 21, and the piston rod of the pushing cylinder 2 passes through the limiting hole 22. The piston rod of the pushing cylinder 2 expands and contracts along the limiting hole 22, and the limiting hole 22 plays a role in limiting the piston rod.

[0034] For a pin insertion device of an earplug box of the present utility model, the earplug box 5 is placed in the material placing groove 11, and the pin 52 is inserted into one end of the installation groove 51 of the earplug box 5. Subsequently, the pushing cylinder 2 controls the push pin 3 to move towards the earplug box 5. The push pin 3 moves in the limiting channel 44 and pushes the pin 52 to the target position in the installation groove 51. Among them, the limiting channel 44 plays a role in limiting the movement of the push pin 3, so that the pushing direction of the push pin 3 on the target pin 52 always remains on the same straight line, avoiding the push pin 3 pushing the pin 52 crooked and causing pin jamming. After installing the pin 52, after the push pin 3 resets, the earplug box 5 is taken off.

[0035] The preferred embodiments of the present utility model have been specifically described above, but the present utility model is not limited to the described embodiments. Those skilled in the art can also make various equivalent modifications or substitutions without departing from the spirit of the present utility model, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
