Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and in particular to an auxiliary folding device for processing packaging cartons. Background Technology

[0002] In the modern logistics and commodity packaging industry, cardboard boxes are one of the most important forms of transport packaging. The forming and sealing process usually requires precise folding of the cardboard. To improve production efficiency and folding quality, workers often use handheld auxiliary folding devices to press and straighten the lid or specific parts of the cardboard box to ensure that the fold lines are straight and in place.

[0003] Currently, the most common folding aids on the market are relatively simple in structure, typically consisting of a hand grip and a working end for contacting the cardboard box. To ensure structural stability, the grip and working end are usually integrally molded or fixedly connected, resulting in a constant relative angle between them.

[0004] However, in actual processing, due to the varying sizes and depths of cartons, and the diversity of folding processes (e.g., folding the bottom cover versus folding the top cover), operators often need to apply force at different angles and postures. When using this type of fixed auxiliary device, operators have to frequently adjust their wrist and even body postures to adapt to different operational needs. This not only significantly increases the complexity and labor intensity of the operation but also makes it difficult to guarantee the stability and consistency of each folding operation, thus affecting overall processing efficiency and product quality.

[0005] Therefore, this utility model proposes an auxiliary folding device for processing packaging cartons to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of fixed working angles in existing auxiliary folding devices for packaging carton processing, which make it difficult to adapt to changing operational needs and result in complex operation and low efficiency, this utility model aims to provide an auxiliary folding device for packaging carton processing with an improved structure that can effectively solve the above problems.

[0007] This utility model provides an auxiliary folding device for processing packaging cartons, comprising: a handle, a support plate, and a housing rotatably connected to the support plate; and a positioning mechanism.

[0008] The positioning mechanism is used to lock the housing to the support plate at different angles. The positioning mechanism includes multiple slots opened on the housing, a lever slidably disposed on the support plate, a lever fixedly connected to the lever and used to selectively engage with any of the slots, a limiting post fixed to the support plate, and a spring sleeved on the outer wall of the limiting post.

[0009] Furthermore, the two ends of the spring abut against the support plate and the lever respectively, so as to be compressed when the lever slides under external force, and to drive the lever to reset after the external force is released.

[0010] Preferably, the plurality of slots are arranged in a circumferential array along the rotation path of the housing relative to the support plate.

[0011] Preferably, the positioning mechanism further includes a limiting component, which is used to guide and limit the sliding process of the toggle block.

[0012] Furthermore, the limiting component includes a limiting groove formed on the support plate and a limiting block formed on the lever and slidingly engaged with the limiting groove.

[0013] Preferably, the positioning mechanism further includes a sliding plate, which is fixed to the support plate, and the lever is slidably connected to the sliding plate.

[0014] Preferably, the support plate and the grip are slidably connected; the device further includes an adjustment mechanism for locking the support plate onto the grip along its sliding path.

[0015] Furthermore, the adjustment mechanism includes an adjustment groove formed on the support plate, a fixing groove disposed on the grip, a stud passing through the fixing groove and the adjustment groove, and a rotating plate rotatably connected to the grip and fixedly connected to the stud. The rotating plate is used to drive the stud to rotate so as to clamp and fix the support plate to the grip.

[0016] In one specific implementation, the adjustment groove is a strip-shaped groove extending along the length of the support plate.

[0017] This utility model has the following beneficial effects: 1. This utility model, by setting a positioning mechanism, which uses the cooperation of a toggle block, a locking block and multiple slots, and the elastic force of a spring to achieve reset and locking, solves the problem that the existing auxiliary folding device has a fixed working angle and cannot adapt to multi-angle working scenarios. It achieves the technical effect of being able to conveniently adjust the working angle of the shell, thereby adapting to multiple scenarios and improving the adaptability of the device.

[0018] 2. This utility model, by setting an adjustment mechanism, which drives the stud through a rotating plate to lock and release the sliding connection between the support plate and the handle, solves the problem that the existing auxiliary folding device has a fixed working range and is difficult to match different sizes of cartons. It achieves the technical effect of flexibly adjusting the effective working range of the device, thereby improving the practicality of the device.

[0019] 3. This utility model solves the problem of shaking and instability that may occur during the adjustment process by adding a limiting component consisting of a limiting block and a limiting groove to the positioning mechanism, and cooperating with the sliding plate to support the shift block. This achieves the technical effect of making the angle positioning operation more stable and the locking more reliable. At the same time, the coordinated work of the positioning mechanism and the adjustment mechanism enables the device to cope with a variety of complex working conditions, and the overall stability and applicability are significantly enhanced.

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0023] Example: Please refer to Figures 1 to 4This utility model provides an auxiliary folding device for processing packaging cartons, which aims to solve the problem that existing auxiliary folding devices for processing packaging cartons have a simple structure and are difficult to adapt to the operational needs of different specifications and angles.

[0024] like Figure 1 As shown, the auxiliary folding device for packaging carton processing includes a handle 3 for the operator to hold, a support plate 2 slidably connected to the handle 3, and a housing 1 rotatably connected to the support plate 2. The device is provided with a positioning mechanism 4 for locking the housing 1 to the support plate 2 at different angles. The positioning mechanism 4 includes a lever 41 slidably disposed on the support plate 2, a locking block 46 fixedly connected to the lever 41, and multiple slots 47 for selectively engaging with the locking block 46 on the housing 1. The multiple slots 47 are arranged in a circumferential array along the rotation path of the housing 1 relative to the support plate 2. A limit post 43 is also fixed on the support plate 2, and a spring 44 is sleeved on the outer wall of the limit post 43. The two ends of the spring 44 abut against the support plate 2 and the lever 41, respectively. The spring 44 is used to compress the lever 41 when it slides under external force, and to drive the lever 41 to reset after the external force is released, so that the locking block 46 is locked into one of the slots 47, thereby realizing the angle locking between the housing 1 and the support plate 2.

[0025] Please refer to the following carefully. Figure 1 , Figure 3 and Figure 4 The core structure will be described in detail below: The limiting component 42 includes a limiting block 421 and a limiting groove 422. The limiting block 421 is formed on the push block 41, and the limiting groove 422 is formed on the support plate 2. The limiting block 421 and the limiting groove 422 are slidably engaged. Its function is to provide precise guidance and limiting for the sliding movement of the push block 41, ensuring that the push block 41 runs stably along a predetermined straight path when pushing the card block 46 to move. It effectively prevents the push block 41 from deflecting or shaking when subjected to force, so as to ensure that the card block 46 can accurately disengage from and engage with the card groove 47, thereby improving the stability and reliability of the positioning mechanism 4.

[0026] Meanwhile, the positioning mechanism 4 also includes a slide plate 45, which is fixed on the support plate 2. The lever 41 is slidably connected to the slide plate 45. The presence of the slide plate 45 serves as a support base for the lever 41, making the sliding connection of the lever 41 more stable and effectively improving the mechanical rigidity and stability of the entire positioning mechanism 4 during frequent operation.

[0027] Regarding the way the spring 44 is fitted, the spring 44 surrounds the outer periphery of the limiting post 43. The limiting post 43 has a cylindrical structure, and the spring 44 is a compression spring. This surrounding fit structure ensures that when the spring 44 is squeezed by the push block 41 and undergoes elastic deformation, the spring 44 can stably extend and retract along the axial direction of the limiting post 43, thereby accurately providing a reset elastic force to push the push block 41 and the locking block 46 back to their original position.

[0028] In a preferred embodiment, in order to adjust the working range of the entire device, the support plate 2 and the handle 3 are slidably connected. The device also includes an adjustment mechanism 5, which is used to lock the support plate 2 at any position on its sliding path onto the handle 3, thereby adjusting the working distance of the housing 1 to adapt to packaging cartons of different sizes.

[0029] Further, please refer to Figure 1 and Figure 2 The adjustment mechanism 5 includes an adjustment groove 53 on the support plate 2, a fixing groove 54 on the handle 3, a stud 52 passing through the fixing groove 54 and the adjustment groove 53 in sequence, and a rotating plate 51 rotatably connected to the handle 3. The rotating plate 51 is fixedly connected to the stud 52. The rotating plate 51 is used to drive the stud 52 to rotate. The clamping force generated by the threaded engagement firmly clamps and fixes the support plate 2 to the handle 3. When the distance needs to be adjusted, the clamping force can be released by rotating the rotating plate 51 in the opposite direction, so that the support plate 2 can slide relative to the handle 3.

[0030] As a specific implementation scheme, the adjustment groove 53 is a strip groove extending along the length of the support plate 2. This strip groove structure provides guidance for the sliding of the support plate 2 and limits its maximum sliding stroke, making the entire device more stable and reliable when adjusting the working range.

[0031] The working principle is as follows: When the working angle of housing 1 needs to be adjusted, the operator applies external force to the lever 41 to make it slide. The lever 41 slides on the slide plate 45 and is guided and limited by the limiting block 421 and the limiting groove 422 in the limiting component 42. The movement of the lever 41 squeezes the spring 44 sleeved on the outer wall of the limiting post 43, causing it to undergo elastic deformation. At the same time, the locking block 46 fixedly connected to the lever 41 separates from the currently engaged slot 47. At this time, the lock of housing 1 relative to the support plate 2 is released, and the operator can freely rotate housing 1 to the required angle. When the external force applied to the lever 41 is released, the spring 44 releases its elastic force to push the lever 41 to reset, thereby driving the locking block 46 to engage in the other aligned slot 47, thus relocking housing 1 to the support plate 2 at the new angle, realizing rapid adaptation to the angle requirements under different working scenarios.

[0032] When it is necessary to adjust the working range or distance of the housing 1, the operator rotates the rotating plate 51. The rotating plate 51 drives the stud 52 to rotate through its fixed connection with the stud 52, thereby loosening the clamping force on the support plate 2. At this time, the restriction of the fixing groove 54 on the adjusting groove 53 is released, and the support plate 2 can slide relative to the handle 3 along the length direction of the adjusting groove 53 to adjust to a suitable working distance. After the adjustment is completed, the rotating plate 51 is rotated in the opposite direction, and the stud 52 clamps the support plate 2 and the handle 3 again, thereby completing the adjustment of the working range. Through the coordinated work of the positioning mechanism 4 and the adjusting mechanism 5, the entire device can flexibly adapt to various working conditions, thereby greatly improving the adaptability of the device.

[0033] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
