Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging box production technology, specifically a folding device for packaging box production. Background Technology
[0002] Packaging boxes are mainly used to facilitate transportation, loading and unloading, and warehousing. Common forms include wooden boxes, corrugated solid wood pallets, and also materials such as tin drums or cardboard. To balance portability and practicality, ordinary packaging boxes usually use corrugated cardboard as the main raw material. In the production process, the cut corrugated cardboard needs to go through a folding process to form the basic shape of the packaging box.
[0003] However, traditional folding processes typically involve only simple bending of the cardboard, lacking effective pressure control over the crease area. This can easily lead to problems such as shallow creases and edge springback. These defects not only cause uneven corners and misaligned edges of the carton, affecting its overall appearance, but also weaken the structural stability and load-bearing capacity of the carton, thus increasing the product defect rate. Utility Model Content
[0004] The purpose of this invention is to provide a folding device for packaging box production, which can apply pressure to the bending area during the folding process of corrugated cardboard, thereby improving the quality of the folding operation.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a folding device for packaging box production, comprising a conveyor table, a fixed box fixedly installed at the middle of the bottom of the conveyor table, a second electric push rod fixedly installed at the middle of the bottom of the fixed box, a lifting frame fixedly installed at the output end of the second electric push rod, a dual-axis motor fixedly installed at the middle of the bottom of the inner cavity of the lifting frame, adjusting screws fixedly installed on both sides of the output end of the dual-axis motor, the sides of the adjusting screws being movably connected to the inner cavity of the lifting frame via bearings, an adjusting frame being threadedly connected to the surface of the adjusting screws, a fixed frame fixedly installed at the upper end of the adjusting frame, and a pressure roller being movably connected between the two sides of the fixed frame via bearings.
[0006] As a preferred embodiment, a fixing frame is fixedly connected between the lower ends of both sides of the outer surface of the fixing box, a first electric push rod is fixedly installed at the middle of the top of the fixing frame, a lifting plate is fixedly installed at the output end of the first electric push rod, and pressure frames are fixedly installed at both ends of the bottom of the lifting plate.
[0007] As a preferred embodiment, both ends of the top of the fixed frame are slidably connected to guide vertical rods, and the bottom of the guide vertical rods are fixedly installed on the top of the lifting plate.
[0008] As a preferred embodiment, stainless steel guide rods are fixedly installed on the right ends of both sides of the conveyor platform, and support legs are fixedly installed around the bottom of the conveyor platform.
[0009] As a preferred embodiment, a reinforcing rod is fixedly installed between the upper end of the adjustment frame and the surface of the fixed frame.
[0010] As a preferred embodiment, a maintenance plate is fixedly installed on the right side of the fixed box by bolts, guide rods are fixedly installed around the bottom of the fixed box, and guide plates are fixedly installed around the outer surface of the lifting frame, with the surface of the guide plate slidably connected to the surface of the guide rod.
[0011] As a preferred embodiment, a guide crossbar is slidably connected between the lower ends of the two adjustment frames, and the two sides of the guide crossbar are fixedly installed on the upper end of the inner cavity of the lifting frame.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] This invention uses a second electric push rod to raise the lifting frame, adjusting frame, and fixing frame, enabling the pressure rollers to push and lift the two ends of the corrugated cardboard in the middle area of the conveyor table. A dual-axis motor drives the adjusting screw to rotate, causing the two sets of pressure rollers to move closer together. While pushing and folding the lifted ends of the corrugated cardboard towards the center, the folded parts of the cardboard are rolled and pressed to form deeper creases. This effectively avoids edge springback problems caused by shallow creases, significantly improving the quality of corrugated cardboard folding operations during packaging box production and reducing product defect rates caused by folding issues.

[0019] 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.
[0020] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0021] The components in this application, such as the conveyor table 1, fixed box 2, fixed frame 3, support leg 4, first electric push rod 5, lifting plate 6, guide vertical rod 7, pressure frame 8, pressure roller 9, maintenance plate 10, stainless steel guide rod 11, second electric push rod 12, lifting frame 13, guide plate 14, guide rod 15, adjusting frame 16, fixed frame 17, reinforcing rod 18, dual-axis motor 19, adjusting screw 20, and guide crossbar 21, are all general standard parts or parts known to those skilled in the art. Their structure and principle are common knowledge and can be learned by those skilled in the art through technical manuals or conventional experimental methods.
[0022] Example 1:
[0023] Please see Figures 1-4 As shown, this utility model provides a folding device for packaging box production, including a conveyor table 1, a fixed box 2 fixedly installed at the middle of the bottom of the conveyor table 1, a second electric push rod 12 fixedly installed at the middle of the bottom of the fixed box 2, a lifting frame 13 fixedly installed at the output end of the second electric push rod 12, a dual-axis motor 19 fixedly installed at the middle of the bottom of the inner cavity of the lifting frame 13, adjusting screws 20 fixedly installed on both sides of the output end of the dual-axis motor 19, the side of the adjusting screw 20 being movably connected to the inner cavity of the lifting frame 13 through bearings, an adjusting frame 16 being threadedly connected to the surface of the adjusting screw 20, a fixed frame 17 fixedly installed at the upper end of the adjusting frame 16, and a pressure roller 9 being movably connected between the two sides of the fixed frame 17 through bearings.
[0024] In this technical solution, when the corrugated cardboard after creasing needs to be folded, the extension of the second electric push rod 12 can push the lifting frame 13, adjusting frame 16, fixing frame 17 and pressure roller 9 upward. Under the action of the pressure roller 9 moving upward, it can contact the two ends of the corrugated cardboard in the middle area of the conveyor table 1, and push the two ends of the corrugated cardboard upward and tilt them up. At the same time, the dual-axis motor 19 drives the adjusting screw 20 to rotate, and drives the two sets of adjusting frames 16, fixing frames 17 and pressure roller 9 to move towards each other. Under the action of the pressure roller 9 moving, the tilted parts of the corrugated cardboard at both ends can be pushed and folded towards the middle. At the same time, the pressure roller 9 can roll and press the folded part of the corrugated cardboard, so that a deeper crease can be formed in this area, avoiding edge rebound due to shallow creases, and effectively improving the quality of corrugated cardboard folding operation.
[0025] It should be noted that the coordinated operation of the various electrical components in this device can be uniformly coordinated through the corresponding control unit to ensure that the folding process can be carried out in the predetermined sequence. As this is prior art, it will not be described in detail here.
[0026] Example:
[0027] Based on Embodiment 1, this utility model is as follows: Figure 1 and Figure 2 As shown, a fixed frame 3 is fixedly connected between the lower ends of both sides of the outer surface of the fixed box 2. A first electric push rod 5 is fixedly installed at the middle of the top of the fixed frame 3. A lifting plate 6 is fixedly installed at the output end of the first electric push rod 5. Pressure frames 8 are fixedly installed at both ends of the bottom of the lifting plate 6. Guide vertical rods 7 are slidably connected to both ends of the top of the fixed frame 3. The bottom of the guide vertical rod 7 is fixedly installed on the top of the lifting plate 6.
[0028] In this technical solution, the fixed frame 3 can support the first electric push rod 5 while the first electric push rod 5 extends and drives the lifting plate 6 and the pressure frame 8 to move downward. This causes the pressure frame 8 to apply pressure to the corrugated cardboard to be folded below, preventing the corrugated cardboard from shifting during subsequent folding. The guide rod 7 is used to guide the lifting plate 6.
[0029] It should be noted that the left end of the pressure frame 8 is open, and during operation, both ends of the corrugated cardboard will be folded into the opening of the pressure frame 8. Therefore, the pressure frame 8 does not obstruct the folded parts of the corrugated cardboard.
[0030] Example 3:
[0031] Based on Embodiment 1, this utility model is as follows: Figures 1-4As shown, stainless steel guide rods 11 are fixedly installed on the right ends of both sides of the conveyor table 1, support legs 4 are fixedly installed around the bottom of the conveyor table 1, reinforcing rods 18 are fixedly installed between the upper end of the adjusting frame 16 and the surface of the fixed frame 17, maintenance plate 10 is fixedly installed on the right side of the fixed box 2 by bolts, guide rods 15 are fixedly installed around the bottom of the fixed box 2, guide plates 14 are fixedly installed around the outer surface of the lifting frame 13, the surface of the guide plate 14 is slidably connected to the surface of the guide rod 15, and guide crossbars 21 are slidably connected between the lower ends of the two adjusting frames 16, with both sides of the guide crossbars 21 fixedly installed at the upper end of the inner cavity of the lifting frame 13.
[0032] In this technical solution, the stainless steel guide rod 11 provides support and guidance for both ends of the folded corrugated cardboard on the right side of the conveyor table 1. The support leg 4 provides support for the bottom of the conveyor table 1. The reinforcing rod 18 effectively improves the connection strength between the adjusting frame 16 and the fixed frame 17. The maintenance plate 10 facilitates maintenance of the internal components of the fixed box 2. The guide rod 15 and guide plate 14 guide the lifting frame 13 to prevent it from shifting during movement. The guide crossbar 21 guides the adjusting frame 16 to prevent it from rotating during movement.
[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
