Description

Technical Field

[0001] This utility model relates to the field of cardboard box forming technology, and in particular to a cardboard box forming device for cardboard box processing. Background Technology

[0002] Carton forming involves folding pre-printed and grooved cardboard along predetermined creases and then gluing the edges together with glue or tape to create the three-dimensional shape of the carton.

[0003] For example, CN220576726U discloses a carton forming device for carton processing, including: a telescopic column, an installation sleeve movably connected to the outer surface of the telescopic column, an auxiliary block fixedly installed on one side of the installation sleeve, an upper connecting sleeve movably connected to the outer surface of the telescopic column, a lower connecting sleeve movably connected below the upper connecting sleeve, a support block fixedly installed below the lower connecting sleeve, a connecting rod fixedly installed on one side of the support block, a fixing sleeve fixedly installed on the outer surface of the connecting rod, an arc-shaped rod movably connected above the fixing sleeve, and a clamping frame fixedly installed below the arc-shaped rod.

[0004] However, in the existing technology, due to the insufficient stiffness of the cardboard, it is easy to deform when external force is applied without sufficient support. If workers apply external force to the side wall of the carton due to improper operation, it will cause the side wall of the carton to dent. This will not only make the appearance uneven and affect the overall packaging image of the product, but also weaken the overall structural strength of the carton. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art where improper operation by humans can cause accidental external force to be applied to the side wall of a carton, resulting in dents in the side wall. Therefore, this invention proposes a carton forming device for carton processing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cardboard box forming device for cardboard box processing, comprising a support frame, four limiting mechanisms installed on the outer surface of the support frame, a support mechanism installed above the support frame, and a control mechanism installed on one side of the top of the support frame;

[0007] The support mechanism includes four connecting rods. A rotating sleeve is rotatably connected to the outer surface of each connecting rod. A support plate is fixedly connected to one side of each rotating sleeve. A second rotating frame is fixedly connected to both ends of each connecting rod. A connecting frame is rotatably connected to the inner side of each of the two second rotating frames.

[0008] The control mechanism includes a track plate, a movable block is slidably connected to the inner side of the track plate, a cylinder is provided on one side of the movable block, and a first rotating frame is rotatably connected to both ends of the cylinder. One of the first rotating frames is fixedly connected to the top of the track plate, and the other first rotating frame is fixedly connected to the side wall of the movable block.

[0009] Preferably, the bottom of one of the connecting frames is fixedly connected to the movable block, and the bottom of the other connecting frame is fixedly connected to the top of the support frame.

[0010] Preferably, the limiting mechanism includes a fixed frame, a limiting sleeve is fixedly connected to one side of the fixed frame, and a movable rod is slidably connected to the inner side of the limiting sleeve.

[0011] Preferably, a limiting plate is fixedly connected to one end of the movable rod, and a limiting ring is fixedly connected to the outer surface of one end of the movable rod.

[0012] Preferably, a spring is provided between the limiting ring and the fixing frame, and the spring is sleeved on the outer surface of the movable rod.

[0013] Preferably, a guide block is fixedly connected to the outer surface of one end of the movable rod, and a groove is provided on the inner side of the limiting sleeve.

[0014] Preferably, the guide block is slidably connected to the groove, and the diameter of one end of the movable rod is larger than the inner diameter of the limiting sleeve.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. In this utility model, the moving block is driven by a cylinder to generate displacement, and the track plate guides it to ensure stable operation. Under the drive of the moving block, the connecting frame works in coordination to push the connecting rod to move synchronously and evenly push the four support plates to arch and form a stable frame. The support carton does not deform or collapse during the forming and bonding process. The uniform arching of the support plates effectively stabilizes the shape of the carton, ensuring that its shape remains unchanged and providing reliable support. When moving in the reverse direction, the support plates move gently in the reverse direction, making it easy to remove the formed carton and carry out subsequent processing.

[0017] 2. In this utility model, the rotation of the movable rod and the sliding of the guide block along the groove ensure precise positioning of the carton. Driven by the movable rod, the elasticity of the spring causes the limiting ring to shift slightly, playing a dual role of buffering and transmitting force. The sliding of the limiting plate gradually presses against the side wall of the carton, ensuring its stable position and preventing displacement. The support plate provides additional support to help maintain the stability of the carton and work together to complete precise positioning. The spring design ensures that the carton is always in the preset position throughout the positioning process, effectively avoiding positioning errors and ensuring the smooth progress of subsequent operations. The coordinated work of the entire system improves positioning accuracy and stability, providing a reliable guarantee for the processing and subsequent handling of the carton.

[0023] 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.

[0024] 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.

[0025] Example 1: As Figure 1- Figure 3 As shown, this utility model provides a carton forming device for carton processing, including a support frame 1, four limiting mechanisms 3 installed on the outer surface of the support frame 1, a support mechanism 4 installed above the support frame 1, and a control mechanism 2 installed on one side of the top of the support frame 1.

[0026] The support mechanism 4 includes four connecting rods 44. A rotating sleeve 42 is rotatably connected to the outer surface of the connecting rods 44. A support plate 41 is fixedly connected to one side of the rotating sleeve 42. A second rotating frame 45 is fixedly connected to both ends of the connecting rods 44. A connecting frame 43 is rotatably connected to the inner side of each of the two second rotating frames 45.

[0027] The control mechanism 2 includes a track plate 23, with a movable block 24 slidably connected to the inner side of the track plate 23. A cylinder 22 is provided on one side of the movable block 24, and both ends of the cylinder 22 are rotatably connected to a first rotating frame 21. One of the first rotating frames 21 is fixedly connected to the top of the track plate 23, and the other first rotating frame 21 is fixedly connected to the side wall of the movable block 24. The bottom of one connecting frame 43 is fixedly connected to the movable block 24, and the bottom of the other connecting frame 43 is fixedly connected to the top of the support frame 1.

[0028] The specific settings and functions of this embodiment are described below. When cylinder 22 operates, the driving force of cylinder 22 displaces the moving block 24. At this time, the moving block 24 moves smoothly under the constraint of track plate 23. Track plate 23 acts as a guide, ensuring that the moving block 24 remains stable during operation and avoiding deviation from the trajectory. As the moving block 24 moves, the connecting frame 43 is driven. One connecting frame 43 moves in a straight line, while the other connecting frame 43 is connected to the support frame 1 and is in a fixed state, thus forming a driving and fixing mechanism.

[0029] Simultaneously, as the moving block 24 operates, the other two connecting frames 43 begin to move, driving the connecting rods 44 to move through linkage with the second rotating frame 45. At this time, the moving connecting frame 43 works in coordination with the other three connecting frames 43 to ensure that the four connecting rods 44 move synchronously. With the coordinated movement of the connecting rods 44, the four support plates 41 are pushed evenly, beginning to arch and form a frame. The arching of these support plates 41 serves to support the cardboard box to be formed, preventing deformation or dents during the gluing process.

[0030] At this point, the carton is supported by four support plates 41, ensuring that the carton does not collapse or deform during the forming and gluing process. The uniform arching of the support plates 41 plays a key role in supporting and stabilizing the shape of the carton. As the four support plates 41 form a stable frame, the carton is firmly supported, ensuring that its shape remains unchanged, thereby providing reliable support during the carton gluing process.

[0031] During the reverse movement, the support plate 41 will move accordingly in the opposite direction, gently arching the already formed carton. The purpose of this action is to facilitate the quick retrieval of the formed carton. At the same time, the reverse movement design also makes it convenient for workers or automated equipment to perform subsequent processing or handling of the formed carton.

[0032] Example 2: Figure 4 As shown, the limiting mechanism 3 includes a fixed frame 31, a limiting sleeve 32 fixedly connected to one side of the fixed frame 31, and a movable rod 33 slidably connected to the inner side of the limiting sleeve 32. A limiting plate 34 is fixedly connected to one end of the movable rod 33, and a limiting ring 35 is fixedly connected to the outer surface of one end of the movable rod 33. A spring 36 is provided between the limiting ring 35 and the fixed frame 31, and the spring 36 is sleeved on the outer surface of the movable rod 33. A guide block 37 is fixedly connected to the outer surface of one end of the movable rod 33, and a groove 38 is formed on the inner side of the limiting sleeve 32. The guide block 37 is slidably connected to the groove 38, and the diameter of one end of the movable rod 33 is larger than the inner diameter of the limiting sleeve 32.

[0033] The overall effect of this embodiment is that, during the positioning of the carton, the rotation of the movable rod 33 ensures precise alignment between the guide block 37 and the groove 38. When the movable rod 33 begins to rotate, the guide block 37 slides along the groove 38, ensuring smooth movement of the movable rod 33 within the limiting sleeve 32. At this time, the elasticity of the spring 36 comes into play, pushing the limiting ring 35 to make a slight displacement within a limited space. The limiting ring 35 not only acts as a buffer in this process but also transmits the force to the movable rod 33.

[0034] The force generated by the movement of the movable rod 33 acts on the limiting plate 34, causing the limiting plate 34 to slide along a predetermined path. As the limiting plate 34 moves, the side wall of the carton is gradually compressed, positioning it precisely. At this time, the pressure between the limiting plate 34 and the side wall of the carton ensures the stability and accuracy of the carton during the positioning process, thus laying the foundation for subsequent processing or operations.

[0035] The support plate 41 plays a crucial role in this process. It provides additional support, ensuring the carton does not shift during positioning and assisting in maintaining its stability. Through coordination with the movable rod 33 and the limiting plate 34, the support plate 41 helps to provide stable support around the carton, achieving precise positioning.

[0036] As the movable rod 33 rotates, the guide block 37 can slide smoothly along the groove 38, ensuring the smoothness of the entire system. The pressure provided by the spring 36 makes the limiting plate 34 fit tightly against the side wall of the carton, further enhancing the carton's fixing effect. At the same time, the elastic design of the spring 36 ensures that the carton can always remain in the preset position during different operations, avoiding positioning errors caused by external force interference.

[0037] The device's operation and working principle are as follows: When cylinder 22 operates, it pushes the moving block 24 to move. During movement, the moving block 24 is restricted by the track plate 23, ensuring smooth movement. As the moving block 24 moves, it drives one of the connecting frames 43 to move linearly, while another connecting frame 43 is fixed and connected to the support frame 1. The remaining two connecting frames 43 then begin to move. The linearly moving connecting frame 43 then drives the connecting rod 44 to move via the second rotating frame 45. When this connecting frame 43 moves, it, in coordination with the other three connecting frames 43, causes the four connecting rods 44 to move, thereby arching the four support plates 41 and supporting the carton to be formed. The four support plates 41 form a frame, providing support during carton bonding. During this process, the carton is supported, preventing dents during forming.

[0038] During carton positioning, the rotation of the movable rod 33 aligns the guide block 37 with the groove 38, allowing the movable rod 33 to slide within the limiting sleeve 32. During this process, the elasticity of the spring 36 pushes the limiting ring 35 to move, transmitting the force to the movable rod 33, which in turn moves the limiting plate 34, causing the limiting plate 34 to press against the side wall of the carton. Furthermore, the support plate 41 assists in positioning the carton. As the movable rod 33 moves, the guide block 37 slides along the groove 38, ensuring the limiting plate 34 fits tightly against the carton under the action of the spring 36.

[0039] 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.
