Description

Technical Field

[0001] This utility model belongs to the technical field of box gluing machines, and specifically relates to a box folding mechanism for a box gluing machine. Background Technology

[0002] A carton gluing machine or carton gluing production line is a mechanical device used in carton factories to glue and fold cartons. It generally includes a conveying mechanism, a correction and limiting mechanism, a folding mechanism, and a gluing mechanism. Currently, the most common folding mechanism is the gradient folding mechanism, which has gradient pressure bars on both sides of the conveying mechanism. The gradient pressure bars gradually change along the height direction (Z-axis) and the width direction (Y-axis). As the conveying mechanism moves and the gradient pressure bars act, the sides of the carton are lifted and folded inward. Although this gradient folding mechanism has high folding efficiency and good continuity, it results in a longer carton gluing machine and a larger volume, which also increases costs. It may not be very suitable for small-batch production or small-scale workshops. Utility Model Content

[0003] This invention provides a box-folding mechanism for a box-gluing machine, which can solve the problems pointed out in the background art.

[0004] A box-folding mechanism for a box-gluing machine includes a frame with box-folding assemblies on both sides. Each box-folding assembly includes a sliding main frame, a Y-axis reciprocating drive assembly, a Z-axis reciprocating drive assembly, and a box-folding rod assembly. The sliding main frame is slidably connected to the frame, and one end of the box-folding rod assembly is hinged to the sliding main frame. The Z-axis reciprocating drive assembly drives the box-folding rod assembly to reciprocate in the Z-axis plane, and the Y-axis reciprocating drive assembly drives the box-folding rod assembly to reciprocate along the Y-axis.

[0005] Preferably, the Y-axis reciprocating drive assembly drives the sliding main frame to reciprocate along the Y-axis, and the sliding main frame is slidably connected to the mechanism frame via a first slide rail.

[0006] Preferably, the Y-axis reciprocating drive assembly includes a Y-axis drive motor fixed on the sliding main frame, a traveling gear, and a rack arranged in the Y-axis direction.

Detailed Implementation

[0012] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment. Example

[0013] like Figure 1-4As shown in the figure, the folding mechanism of the gluing machine provided by this utility model includes a mechanism frame 1. Folding assemblies are respectively provided on both sides of the mechanism frame 1. The folding assembly includes a sliding main frame 21, a Y-axis reciprocating drive assembly, a Z-axis reciprocating drive assembly, and a folding rod assembly. The sliding main frame 21 is slidably connected to the mechanism frame 1. One end of the folding rod assembly is hinged to the sliding main frame 21. The Z-axis reciprocating drive assembly drives the folding rod assembly to reciprocate in the Z-axis plane, and the Y-axis reciprocating drive assembly drives the folding rod assembly to reciprocate along the Y-axis.

[0014] Specifically, the Y-axis reciprocating drive assembly drives the sliding main frame 21 to reciprocate along the Y-axis, and the sliding main frame 21 is slidably connected to the mechanism frame 1 via the first slide rail 22.

[0015] Specifically, the Y-axis reciprocating drive assembly includes a Y-axis drive motor 231 fixed on the sliding main frame 21, a traveling gear 232, and a rack 233 arranged in the Y-axis direction. The traveling gear 232 is connected to the output end of the Y-axis drive motor 231 and meshes with the rack 233 arranged on the mechanism frame 1.

[0016] Specifically, the Z-axis reciprocating drive assembly includes a Z-axis drive motor 241 fixed on the sliding main frame 21, a second slide rail 242, and a movable connecting rod 243. The lower end of the movable connecting rod 243 is hinged to the folding box rod assembly, and the upper end is hinged to the slide block 244 of the second slide rail 242. The Z-axis drive motor 241 drives the slide block 244 to reciprocate along the Z-axis.

[0017] Specifically, the Z-axis drive motor 241 drives the slide block 244 to slide back and forth along the Z-axis via the synchronous belt 245. The slide block 244 is connected to the belt body of the synchronous belt 245. The folding box rod assembly includes a swing arm 251 arranged in the Y-axis and a swing rod 252 arranged in the X-axis connected to the end of the swing arm 251. One outer end of the swing arm 251 is hinged to the sliding main frame 21 via a hinge seat. The swing arm 251 is hinged to the movable connecting rod 243.

[0018] Special combination Figure 1-2 ,in Figure 1The full structure of the folding and positioning device is not shown. A folding and positioning device can also be installed between the folding components on both sides. This includes a connector 51 along the X-axis and parallel positioning plates 52. Both ends of the connector 51 can be connected to the gluing equipment frame via Y-axis slide rails, allowing for relative Y-axis position adjustment to accommodate different carton sizes 3. The two parallel positioning plates 52 position and limit the folding process. The front positioning plate 52 can be fixed to the connector 51, and the rear positioning plate 52 can be connected to the X-axis slide rails. On the X-axis slide of the moving guide rail 53, the X-axis positioning motor 54 and the X-axis synchronous belt 55 drive the X-axis slide to slide back and forth to meet the needs of different sizes of cartons 3; in addition, the X-axis sliding guide rail 53 is connected to the Z-axis slide of the Z-axis slide rail 56, and the Z-axis slide is driven to slide back and forth by the Z-axis positioning motor 57 and the Z-axis synchronous belt 58, which drives the rear positioning plate 52 to rise and fall, so that it can switch between idle position and positioning position. The idle position can prevent it from interfering with the forward conveying of the carton 3. The Z-axis slide rail 56 is fixed.

[0019] The actions of each of the above components need to be controlled by a control system (which can be based on PLC) in conjunction with position switches, etc. The working principle of this utility model is as follows: The carton 3 is conveyed by a conveying mechanism to a set position. The position of the carton 3 can be detected by a position switch. After reaching the set position, the conveying mechanism stops. Several pneumatic suction heads 4 are set at corresponding positions on the frame of the conveying mechanism for adsorbing, fixing and stabilizing the carton 3 during the folding process. In particular, when the two sides of the carton are folded upwards, the pneumatic suction heads 4 are needed to adsorb and fix the carton 3. The control system controls the Y-axis reciprocating drive assembly and the Z-axis reciprocating drive assembly to move. Specifically, the Y-axis reciprocating drive assembly drives the folding rod assembly. The conveyor moves inward along the Y-axis, while the Z-axis reciprocating drive assembly drives the folding rod assembly to move upward along the Z-axis. This gradually lifts the cardboard boxes on both sides. After reaching the set position (i.e., after the cardboard boxes on both sides have passed the vertical position), the Z-axis reciprocating drive assembly drives the folding rod assembly to move downward along the Z-axis, gradually pressing the cardboard boxes on both sides downward and making the left and right cardboard boxes stick together. At the same time, the Y-axis reciprocating drive assembly drives the folding rod assembly to move outward along the Y-axis to return to its original position. The conveying mechanism then operates again, conveying the next cardboard box 3 to the set position, and repeating the above actions.

[0020] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
