[0002] Cardboard boxes are the most widely used packaging products. Depending on the materials used, there are corrugated cardboard boxes, single-layer cardboard boxes, etc., and they come in various specifications and models. Cardboard boxes commonly have three or five layers, while seven-layer boxes are less common. Each layer consists of linerboard, corrugated paper, core paper, and face paper. Linerboard and face paper can be made of kraft paper or kraft paper, while the core paper is made of corrugated paper. The colors and textures of various types of paper are different, and the paper produced by different manufacturers is also different. A handle attaching machine is a processing device used to assist in the process of attaching handles to cardboard boxes.

[0003] Currently, existing cardboard inserters are mainly divided into inserters with handles and inserters without handles. Inserters with handles typically use a gripping mechanism to place the handle at the appropriate position on the cardboard box. Then, utilizing the T-shaped structure at both ends of the handle, and with the help of guide grooves located below the double conveyor belts, the handle is propelled past the cardboard box from one side of the handle to complete the insert. To achieve another inserting method with a handle, this utility model is proposed. Utility Model Content

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Example 1, as Figures 1-4 As shown, this embodiment aims to provide another structural form of a handle inserting machine with handle buckles. To this end, the handle inserting machine for cartons provided in this embodiment includes a double-strip synchronous conveyor 1 for conveying cartons and a handle buckle gripping and conveying mechanism 2 disposed on one side of the double-strip synchronous conveyor 1. The double-strip synchronous conveyor 1 refers to a conveyor belt with a narrow bandwidth only on both sides of the conveyor rollers. The purpose of this is to expose the middle of the conveyor, facilitating insertion from below. The handle buckle gripping and conveying mechanism 2, like existing mechanisms, is mainly used to place the gripped handle buckle above the opening in the paper.

[0020] The above structure is a common existing structure, therefore, it will not be described in detail in this embodiment.

[0021] To provide another way of interleaving, in this embodiment, a handle gripping conveyor 3 is also provided on the side of the dual synchronous conveyor 1 away from the handle gripping conveyor 2. The handle gripping conveyor 3 includes a fixed frame 31 set on one side of the dual synchronous conveyor 1 and a traveling frame 32 that travels in the lateral direction along the fixed frame 31. The main purpose of the lateral travel is to facilitate the placement of handle placement seats or handle conveyor belts on the side of the dual synchronous conveyor 1 to achieve continuous gripping.

[0022] To achieve another interlacing method, in this embodiment, the two ends of the bottom are interlaced simultaneously. To achieve the above objective, in this embodiment, the fixed frame 31 is set below the conveyor belt of the double synchronous conveyor 1. A rotary motor is set on the walking frame 32. The power end of the rotary motor is connected to the lifting cylinder 33. The conveying end of the lifting cylinder 33 is connected to the lifting seat 34. A gripping seat 4 is installed at the bottom of the lifting seat 34. In this embodiment, the gripping seat 4 is generally rectangular. Tilting grooves 41 are set on both sides of the gripping seat 4. The tilting grooves 41 make the two sides of the gripping seat 4 tilted into a U-shape. An external rotor motor 42 is set in the tilting groove 41. A bending rod 43 is set on the external rotor motor 42. The bending rod 43 is a long rod whose main purpose is to bend both ends of the handle for easy insertion. At the same time, in order to maintain the gripping of the handle and maintain the length of the handle after bending, a negative pressure suction cup 44 is provided at the bottom of the gripping seat 4, and the negative pressure suction cup 44 is located close to both sides of the gripping seat 4.

[0023] With the above settings, when the carton (folded state) on the dual synchronous conveyor 1 stops at the designated position, the handle buckle gripping conveyor 2 also grabs the handle buckle from the handle buckle placement seat or the handle buckle conveyor belt, moves it above the carton, places the handle buckle on the carton, and keeps the handle buckle pressed down. Then, the handle gripping and conveying mechanism 3 uses the negative pressure suction cup 44 to grip the handle from the handle placement seat or handle conveyor belt, and then moves it to the bottom of the carton. At this time, the rotary motor works, changing the gripping seat 4 from the bottom of the lifting seat 34 to the top of the lifting seat 34. Then, the outer rotor motor 42 works, the bending rod 43 flips, and flips the T-shaped structure at both ends of the handle upward. Since the negative pressure suction cup 44 is set close to both sides of the gripping seat 4, the entire handle is bent into a U-shape. Then, the lifting cylinder 33 is activated, inserting the handle upward. After the handle is inserted into the carton to the T-shaped connection point, at this time, under the limit of the carton hole, the two ends of the handle will not flip into a T-shape. Then, the outer rotor motor 42 works, the bending rod 43 flips back to its original position, and the lifting cylinder 33 continues to operate, completing the insertion of the handle.

[0024] To achieve the gripping and conveying of the handle buckle, the handle buckle gripping and conveying mechanism 2 provided in this embodiment includes a frame 21 disposed on one side of the double synchronous conveyor 1 and a sliding frame 22 that travels laterally along the frame 21. A lifting frame 23 is disposed on the sliding frame 22, and the lifting frame 23 is vertically and vertically mounted on the frame 21. An adsorption seat 24 is disposed at the bottom of the lifting frame 23, and an adsorption suction cup 25 is disposed at the bottom of the adsorption seat 24. Considering that the adsorption seat 24 has the function of pressing the handle buckle, at least two adsorption suction cups 25 are disposed on the adsorption seat 24.

[0025] The above setup effectively achieves another type of handle with a buckle.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
