Technical Field

[0001] This utility model relates to the technical field of opening hanging holes for packaging bags, specifically a hanging hole device for environmentally friendly packaging bags. Background Technology

[0002] Eco-friendly packaging bag hanging holes refer to holes punched in eco-friendly packaging bags. These holes are typically used to hang the bags for display or carrying. With increasing environmental awareness, more and more businesses and consumers are paying attention to the environmental friendliness of packaging materials. As a result, the demand for eco-friendly packaging bag hanging hole devices is constantly increasing in the market.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4This utility model provides a technical solution: an environmentally friendly packaging bag hanging hole device, including a support frame 1, an electric telescopic rod 2 fixedly installed at the top of the support frame 1, a transmission plate 3 fixedly connected at the middle position of the output end of the electric telescopic rod 2, symmetrically arranged first springs 4 fixedly connected at the bottom of the transmission plate 3, pressure plates 5 fixedly connected at the bottom of each of the first springs 4, and guide rods 6 fixedly connected at the top of each pressure plate 5 corresponding to the hollow position of the first spring 4, the guide rods 6 passing through the transmission plate 3, the guide rods 6 and the transmission plate 3 being slidably connected, and an adjusting plate 7 slidably connected to one side of the support frame 1. A metal spring 8 is fixedly connected to one side near the top of the adjustment plate 7. Several arrayed storage slots 9 are opened on one side of the top of the adjustment plate 7. A second spring 10 is fixedly connected to the inner wall of the bottom of each of the several storage slots 9. A pressing head 11 is fixedly connected to the bottom of each of the several second springs 10. Several arrayed limiting slots 12 are opened on the side of the adjustment plate 7 away from the several storage slots 9. The metal spring 8 is set in relation to the limiting slots 12. A base plate 13 is fixedly connected to the bottom of the adjustment plate 7. The base plate 13 has cutting grooves 14 corresponding to the several pressing heads 11.

[0018] The pressure plate 5 has an arc-shaped structure design. With the output end of the electric telescopic rod 2 as the center, the pressure plate 5 can initially press and position the area where the hanging hole is opened on the environmentally friendly packaging bag. The metal spring 8 has a V-shaped structure design and is made of stainless steel. The limiting groove 12 has a V-shaped cross-section design, which makes it easy for the metal spring 8 to be embedded in the limiting groove 12, thereby limiting the adjustment plate 7. Several storage slots 9 are all stepped structures. Several extrusion blades 11 are slidably connected to the corresponding storage slots 9, which makes it easy for the output end of the electric telescopic rod to extrude the extrusion blades 11 inside the storage slots 9. The extrusion blades 11 are used to open the hanging hole on the environmentally friendly packaging bag. The diameter of the several storage slots 9 increases sequentially from the pressure plate 5 to the metal spring 8. The diameter of the several cutting grooves 14 also increases sequentially from the pressure plate 5 to the metal spring 8, which makes it easy to open hanging holes of different sizes.

[0019] Specifically, when using this utility model, if different sizes of hanging holes need to be made, simply push the adjusting plate 7 and the base plate 13 towards the electric telescopic rod 2. Since the top of the adjusting plate 7 has limiting grooves 12 at different positions, when the limiting plate moves to a certain position, the metal spring 8 will engage with the limiting groove 12. At the same time, the moving adjusting plate 7 and the base plate 13 will drive the adjusted extrusion head 11 and the cutting groove 14 to correspond with the output end of the electric telescopic rod 2. Place the packaging bag between the base plate 13 and the adjusting plate 7, and start the electric telescopic rod. The electric telescopic rod 2 drives the transmission plate 3 to move upward. The moving transmission plate 3 then drives the pressure plate 5 to squeeze and limit the environmentally friendly packaging bag through the first spring 4. When the electric telescopic rod 2 continues to press down, the guide rod 6 will move upward to guide and prevent the first spring 4 from deviating. At the same time, the output end of the electric telescopic rod 2 will squeeze the extrusion head 11. The extrusion head 11, which is squeezed, will then squeeze the packaging bag. When the extrusion head 11 is engaged with the cutting groove 14, the hanging hole is opened.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
