Description

Technical Field

[0001] This utility model relates to the field of automated processing technology for packaging machinery, specifically a folding mechanism for bottled beverage packaging boxes. Background Technology

[0002] In the field of automated processing technology for packaging machinery, the folding and forming process of packaging boxes has become crucial for improving efficiency. For example... Figure 8 As shown, the current packaging box substrate structure used for bottles includes a substrate for supporting the bottom of the bottle. The two sides of the substrate are folded upward to form a first fold plate, which is used to fix the side wall of the bottle. The end of the first fold plate is further folded inward to form a second fold plate, which is used to fix the top of the bottle, thereby realizing the packaging and fixing of the bottle. After the various parts of the packaging box substrate are attached and fixed to the various parts of the bottle, glue is applied for bonding and fixing.

[0003] In the existing folding process, the packaging box base plate structure is generally folded to form a bottom, a first fold plate, and a second fold plate. Then, it is placed in a positioning groove, and the bottle is placed at the bottom position of the packaging box base plate with the help of a feeding component.

[0004] Because most folding mechanisms currently have limited functionality and can only complete a single folding process, it is difficult to achieve a tight fit between multiple processes. For example, one folding mechanism can only complete the pressing and fixing of the second fold plate, while the fixing of the first fold plate requires another folding mechanism or manual assistance. This is insufficient to complete the entire folding process and often requires manual assistance, indicating room for further optimization. Utility Model Content

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] like Figures 1-7 As shown, the frame 1 is an integral frame structure with a horizontally extending shape. At least one folding component 2 is provided below the frame 1 along its length direction. In this embodiment, there are 6 sets, and each set of folding components 2 is evenly distributed along the length direction of the frame 1. The folding components 2 are sleeved on the frame 1.

[0021] The folding assembly 2 includes a pressing unit 3 that is vertically bolted to the bottom of the frame 1, and first folding units 21 that are symmetrically rotated and installed at both ends of the frame 1. The first folding units 21 on both sides are grouped together. In this embodiment, the first folding units 21 are set to 6 groups, and each group of folding assemblies 2 is evenly distributed along the length of the frame 1. The first folding units 21 on both sides are symmetrically distributed on both sides of the pressing unit 3. A tray 4 is provided directly below the pressing unit 3. The tray 4 has a groove-shaped structure with an upper opening. The direction of the upper opening is within the orthographic projection range of the pressing unit 3.

[0022] The output end of the first folding unit 21 can act on the edge of the first folding plate 42 of the packaging box to push the first folding plate 42, which is originally in an outward unfolded state, inward and adhere to the side wall of the bottle to form a lateral wrapping structure; at the same time, it drives the second folding plates 43 to move closer to each other and directly below the pressing unit 3; the pressing unit 3 presses the two second folding plates 43 downward in the vertical direction, so that the two second folding plates 43 adhere downward to the top wall surface of the bottle.

[0023] Specifically, a connecting shaft 11 is horizontally installed on the frame 1. The connecting shaft 11 is parallel to the length direction of the frame 1 and is horizontally set. Its two ends are respectively inserted into the shaft holes on both sides of the frame 1. The outer circumferential surface of the connecting shaft 11 and the inner wall of the shaft hole are rotatably engaged by bearings. Each set of first folding units 21 is rotatably connected to the two ends of the connecting shaft 11 by a fitting method and is symmetrically distributed. The first folding unit 21 can rotate around the connecting shaft 11.

[0024] Furthermore, a first drive unit 22 is also installed on the frame 1. The first drive unit 22 is located above the first folding unit 21 and is used to drive the first folding unit 21 to rotate symmetrically around the connecting shaft 11.

[0025] like Figures 2-4 As shown, the first folding unit 21 includes a rotating part 211, which is an integrally bent rod-shaped structure. A circular through hole is formed at the bend of the rotating part 211. The inner hole of the through hole is fitted with the outer peripheral surface of the connecting shaft 11 through a clearance fit. A driven member 212 is fixedly connected to the bottom of the rotating part 211 by welding. The driven member 212 is perpendicular to the bottom end face of the rotating part 211. A connecting strip 213 is fixedly connected to the top of the rotating part 211 by bolts. The connecting strip 213 is a horizontally extending strip structure. The output end of the first driving unit 22 is driven by the connecting strip 213. The driving connecting strip 213 drives the rotating part 211 and the driven member 212 to rotate synchronously.

[0026] Specifically, the first drive unit 22 includes a drive cylinder 221. The cylinder body of the drive cylinder 221 is fixedly connected to the frame 1 by bolts. The output end of the drive cylinder 221 is connected to the connecting bar 213 by hinge. When the output end of the drive cylinder 221 extends or retracts, it can drive the connecting bar 213 and the rotating part 211 to reciprocate around the connecting shaft 11.

[0027] like Figure 5 As shown, the driven member 212 includes a first folded plate 214, which has a flat plate structure. A second folded plate 215 is integrally formed on its top. The top end face of the second folded plate 215 is fixedly connected to the bottom end face of the rotating part 211 by welding. A third folded plate 216 is integrally formed on the bottom of the first folded plate 214. The third folded plate 216 acts on the first folded plate 42. The first folded plate 214, the second folded plate 215 and the third folded plate 216 together form a Z-shaped fitting structure.

[0028] A rectangular through-hole 217 is provided in the middle of the first folded edge plate 214, and the through-hole 217 extends along the length direction of the first folded edge plate 214.

[0029] like Figures 5-6As shown, the folding assembly 2 also includes at least one set of second folding units 23. In this embodiment, it is set to 6 sets, and each set of second folding units 23 is evenly distributed along the length direction of the frame 1. The second folding units 23 are correspondingly arranged at the upper or lower part of the packaging box.

[0030] The output end of the second folding unit 23 can act on the second folding plate 43 of the packaging box to push one of the second folding plates 43 vertically downward to the top wall of the bottle, so that the other second folding plate 43 naturally covers the upper surface of the first second folding plate 43, forming a superimposed and bonded structure.

[0031] Specifically, the second folding unit 23 includes a fixing member 231, which has a block-shaped structure and a circular through hole at one end. It is fitted with the outer peripheral surface of the connecting shaft 11 by means of an interference fit. The other end of the fixing member 231 is fixedly connected to a folding tooth 232 by welding. The folding tooth 232 has a flat plate structure with the tip facing down, and it acts on the second folding plate 43 of the packaging box.

[0032] A second drive unit 24 is installed at both ends of the connecting shaft 11. The second drive unit 24 is connected to the second folding unit 23 for driving the second folding unit 23 to rotate around the connecting shaft 11.

[0033] When the second folding unit 23 is set on the upper part of the packaging box, the folding tooth 232 is vertically located above the through-hole 217, and the axis of the folding tooth 232 coincides with the axis of the through-hole 217. The folding tooth 232 is inserted downward along the axis of the through-hole 217. The folding tooth 232 is used to press one of the second folding plates 43 downward.

[0034] When the second folding unit 23 is installed at the bottom of the packaging box, it is fixedly connected to the frame 1 via a connector. The connector has a horizontally extending auxiliary connecting shaft at one end facing the packaging box. The auxiliary connecting shaft is parallel to and coaxially arranged with the upper connecting shaft 11. The fixing member 231 of the second folding unit 23 is interference-fitted with the auxiliary connecting shaft through a circular through hole. The folding tooth 232 is located below the through-hole 217, and the axis of the folding tooth 232 coincides with the axis of the through-hole 217. The folding cylinder 241 of the second drive unit 24 is connected to the fixing member 231, driving the folding tooth 232 to axially insert upwards along the through-hole 217. The folding tooth 232 is used to press one of the second folding plates 43 downwards.

[0035] Furthermore, the second drive unit 24 includes a folding cylinder 241, a fixed seat 242, and a rotating arm 243. The fixed seat 242 is block-shaped. The bottom of the folding cylinder 241 is fixedly connected to the side wall of the fixed seat 242 by bolts. The bottom of the fixed seat 242 is fixedly connected to the frame 1 by welding.

[0036] like Figure 7 As shown, the cylinder body of the pressing cylinder 31 is arranged vertically, and the cylinder body of the pressing cylinder 31 is vertically fixed to the bearing plate 32 by bolts. The bearing plate 32 is rectangular flat, and the middle of the bearing plate 32 is provided with an installation through hole that matches the cylinder body of the pressing cylinder 31. The cylinder body of the pressing cylinder 31 is fixedly connected to the upper surface of the bearing plate 32 by a flange.

[0037] The output end of the pressing cylinder 31 extends vertically through the bottom of the bearing plate 32, and the output end is connected to the pressing plate 33 by a thread and a locking nut. The pressing plate 33 is a rectangular flat plate that matches the two second folding plates 43. Its lower surface is provided with a soft material cushioning layer to avoid hard damage to the second folding plates 43 during pressing. When the output end of the pressing cylinder 31 extends downward, the pressing plate 33 can move downward synchronously and cover the upper surface of the second folding plate 43, pressing it downward evenly so that the second folding plate 43 fits against the top wall of the bottle.

[0038] Working principle: First, a base plate 41 carrying the bottle is placed inside the tray 4. In the initial state, the first folding plate 42 in the base plate 41 of the packaging box is unfolded outward. The first driving unit 22 drives the first folding unit 21 to rotate symmetrically around the connecting shaft 11. The first folding unit 21 pushes the first folding plate 42 to fit against the side wall of the bottle to form a lateral wrapping structure. At the same time, through the linkage, the second folding plates 43 on both sides move closer to each other.

[0039] Furthermore, the second driving unit 24 drives the second folding unit 23 to rotate around the connecting shaft 11. The folding teeth 232 of the second folding unit 23 move one of the second folding plates 43 vertically downward to the top wall of the bottle, covering the upper surface of the previous second folding plate 43, forming a superimposed and bonded structure.

[0040] Finally, the output end of the pressing unit 3 extends downward in the vertical direction, causing the pressing plate 33 at the bottom to move downward synchronously. The pressing plate 33 covers the upper surface of the two superimposed second folding plates 43, and by applying downward pressure evenly, the second folding plates 43 are pressed against the top wall surface of the bottle, completing the key pressing process of overall wrapping.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
