Description

TECHNICAL FIELD

[0001] The utility model relates to a packing box technical field, specifically, relate to a packing box indentation depth automatic regulating device. BACKGROUND

[0002] Some special packing boxes, indentation lines need different indentation depth in different positions, for example, to enhance the structural strength of the specific part of the packing box, will add reinforcing material or change the paper layer in the local, when indentation passes these reinforcement areas, compared with other ordinary areas, need deeper indentation depth to ensure the folding effect and the stability of overall structure.

[0003] The existing indentation technology has obvious defects when dealing with this complex demand. If the indentation mode of multiple molding is adopted, try to adjust the depth of the same indentation at different positions step by step through multiple operations, this process not only is extremely cumbersome, greatly reduces the production efficiency, increases the time and labor cost, and each indentation operation will cause a certain degree of damage to the paper. Multiple repeated indentation is easy to cause the paper fiber structure to be damaged excessively, so that the paper appears serious quality problems such as rupture, delamination, which seriously affects the appearance and physical properties of the packing box.

[0004] If it is expected to realize the accurate control of different depths of the same indentation at different positions in a single indentation process, it is often necessary to manufacture a special shaped mold. But customizing this kind of mold not only has high cost, needs to invest a lot of funds for the design and manufacture of the mold. In summary, the existing indentation technology is difficult to effectively meet the complex requirements that the same indentation needs different depths at different positions, and it is urgent to develop a more advanced, efficient and economic indentation technology to adapt to the development trend of diversification and refinement of the packaging industry. INVENTION CONTENTS

[0005] In view of the problems in the prior art, the utility model provides a packing box indentation depth automatic regulating device.

[0006] In order to solve the above technical problems, the utility model solves them through the following technical schemes:

[0007] A packing box indentation depth automatic regulating device, which comprises a mounting rod, a plurality of mutually adhering mounting rings are arranged on the mounting rod, a plurality of pressing plates are evenly arranged on the outer side wall of the mounting ring, the lengths of the pressing plates are different, in use, the mounting ring is rotated according to the requirement, so that the required pressing plate moves to the position directly below the mounting rod, and the pressing plates located in the position directly below the mounting rod jointly constitute an indentation mold.

[0008] The operator rotates the mounting ring at the corresponding position according to the requirement of the specific part of the packaging box for the indentation depth, and moves the pressure plates of different lengths to the position directly below the mounting rod by rotating the mounting ring. These pressure plates directly below constitute the indentation die that meets the current packaging box indentation requirement. The pressure plates of different lengths have different indentation depths, so that different indentation depths can be applied to different positions of the packaging box to meet the different indentation depths required by the special packaging box at different positions on the same indentation. Compared with the traditional method, it does not need multiple indentation operations or customized complex molds, greatly improves the flexibility and efficiency of indentation depth adjustment, and meets the increasingly diversified production requirements of the packaging industry. For example, for packaging boxes with local reinforcement structure, different indentation depth combinations suitable for the reinforcement area and the general area can be quickly adjusted.

[0009] As a preferred, each pressure plate is provided with a shaped hole at the same distance from the axis of the mounting ring, and further comprises a shaped column, which can pass through the shaped hole on the corresponding pressure plate to realize the shaping of the indentation die.

[0010] After selecting the appropriate pressure plates to form the indentation die by rotating the mounting ring, the shaped column is used to ensure the stability and accuracy of the indentation die. Since each pressure plate is provided with a shaped hole at the same distance from the axis of the mounting ring, when the required pressure plates are moved to the position directly below the mounting rod to form the indentation die prototype, the shaped column is passed through the corresponding shaped holes on these pressure plates. In this way, the shaped column, like a "skeleton", fixes the spatial position of each pressure plate, preventing relative displacement of the pressure plates during the indentation operation, thereby realizing the shaping of the indentation die, ensuring the accurate position of each pressure plate during each indentation, and further ensuring the consistency and accuracy of the indentation depth.

[0011] As a preferred, further comprising a nut, and the two ends of the shaped column are provided with external threads matched with the nut.

[0012] The nut is screwed into the position with external threads at both ends of the shaped column. As the nut is tightened, it will generate a pressure force towards the middle of the pressure plates, making the connection between the pressure plates and between the pressure plates and the mounting ring more tight, preventing the pressure plates from loosening or displacing during the indentation process, thereby ensuring that the indentation die maintains a stable structure during the entire indentation operation and ensuring the accuracy of the indentation depth.

[0013] As a preferred, further comprising mounting seats on both sides of the mounting ring, the mounting seats are fixed on the mounting rod, and telescopic rods are installed on the mounting seats, and the two telescopic rods cooperate to fix the shaped indentation die.

[0014] The two telescopic rods move towards each other, and the ends thereof are in contact with the indentation die and apply a certain pressure to clamp and fix the entire indentation die from both sides of the mounting ring. This further enhances the stability of the indentation die on the mounting rod, prevents the overall movement or shaking of the die along the axis of the mounting rod during the indentation process, and ensures accurate indentation operation.

[0015] As a preferred embodiment, the device further comprises a pressing rod and a suspension for mounting the pressing rod; the lower end surface of the pressing rod is fixed with a connecting plate, the pressing rod can drive the connecting plate to move up and down, the left and right ends of the connecting plate extend downward to form extension parts, and the two ends of the mounting rod are fixed on the extension parts.

[0016] The pressing rod and the suspension constitute a power transmission and force application structure. The suspension provides a mounting basis for the pressing rod, ensuring that the pressing rod can stably move up and down. When indentation operation on the paper is required, the pressing rod drives the connecting plate fixed on the lower end surface to move up and down under the action of external power, which can be selected from a motor, hydraulic pressure, etc. Since the left and right ends of the connecting plate extend downward to form extension parts, and the two ends of the mounting rod are fixed on the extension parts, the up-and-down movement of the connecting plate will synchronously drive the mounting rod and the indentation die thereon to move up and down, thereby applying pressure to the paper below and completing the indentation action.

[0017] The pressing plates on the mounting ring are four in number and uniformly distributed on the outer sidewall of the mounting ring.

[0018] Due to their uniform distribution, they can ensure the formation of a relatively stable and symmetrical indentation die structure directly below the mounting rod regardless of the rotation of the mounting ring. BRIEF DESCRIPTION OF DRAWINGS

[0026] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0027] Example

[0028] like Figures 1-5 As shown, an automatic indentation depth adjustment device for packaging boxes is mainly composed of a mounting rod 110, multiple mutually fitting mounting rings 120, a pressure plate 130, a shaping post 140, a nut 150, a mounting base 160, a telescopic rod 1601, a pressure rod 170, and a suspension 180. The number of mounting rings 120 is determined by their own thickness and the length of the indentation. The number of mounting rings 120 is obtained by dividing the indentation length by the thickness of the mounting ring 120.

[0029] The mounting rod 110 serves as the supporting frame for the entire device, and multiple interlocking mounting rings 120 are mounted on it. In this embodiment, four pressure plates 130 of different lengths are evenly distributed on the outer wall of each mounting ring 120. In practical applications, different numbers of pressure plates 130 can be set as needed. Each pressure plate 130 has a shaping hole 1301 at the same distance from the axis of the mounting ring 120. The shaping post 140 can pass through the shaping hole 1301 on the corresponding pressure plate 130, and both ends of the shaping post 140 are provided with external threads that mate with the nut 150.

[0030] Mounting seats 160 are fixed on mounting rods 110 on both sides of mounting ring 120. Telescopic rods 1601 are mounted on mounting seats 160, and the two telescopic rods 1601 can cooperate with each other. In addition, pressure rods 170 and suspensions 180 for mounting pressure rods 170 are provided. A connecting plate 190 is fixed to the lower end face of pressure rod 170. The left and right ends of connecting plate 190 extend downward to form extensions 1901, and the two ends of mounting rod 110 are fixed to the extensions 1901.

[0031] The usage process and principle of the guide mechanism in this embodiment are as follows:

[0032] The operator determines the required combination of the pressing plates 130 according to the requirements of the specific part of the packaging box to be processed. By rotating the mounting ring 120, the pressing plates 130 of different lengths that meet the requirements of the indentation depth are moved to be directly below the mounting rod 110. The lower end surfaces of these pressing plates 130 jointly form the indentation mold required for this time of indentation. The lower end surfaces of the pressing plates 130 can be curved, so that the indentation is more natural.

[0033] The positioning column 140 is inserted through the positioning hole 1301 on the pressing plate 130 directly below the mounting rod 110 to preliminarily fix the position of the pressing plate 130 and realize the positioning of the indentation mold. Then, the screw cap 150 is screwed into the external threaded part at both ends of the positioning column 140. As the screw cap 150 is tightened, the connection between the pressing plates 130 and between the pressing plates 130 and the mounting ring 120 is more secure, ensuring the stability of the mold structure. The extension rods 1601 on the mounting seat 160 are activated to move towards each other, and their ends contact and apply pressure to the indentation mold, clamping the indentation mold from both sides of the mounting ring 120 to prevent the mold from moving or shaking along the mounting rod 110 during indentation.

[0034] The packaging box paper to be indented is placed in the appropriate position below the device, and an external power source such as a motor, hydraulic device, etc. is activated to drive the pressing rod 170 to move up and down under the support of the suspension 180. The pressing rod 170 drives the connecting plate 190 at the lower end to move synchronously. Since the mounting rod 110 is fixed at the extension part 1901 of the connecting plate 190 at both ends, the mounting rod 110 and the indentation mold thereon also move up and down, applying pressure to the paper below to complete the indentation operation.

[0035] By rotating the mounting ring 120 to select different lengths of pressing plates 130 to form the indentation mold, the device can quickly respond to the diversified requirements of different packaging boxes for indentation depth, without the need for complex multiple indentation operations or the customization of expensive special molds, significantly improving production efficiency and enhancing the adaptability of the device to various packaging box production, meeting the increasingly fine and diversified development trend of the packaging industry.

[0036] The coordinated action of the positioning column 140, the screw cap 150, and the extension rods 1601 ensures the stability and accuracy of the indentation mold during the entire indentation process, effectively avoiding problems such as loosening and displacement of the pressing plates 130 and shaking of the mold, thereby ensuring the high consistency of the indentation depth, improving the indentation quality of the packaging box, reducing the rate of defective products, and helping to improve the overall quality of the products.

[0037] In summary, the above is only a preferred embodiment of the present embodiment, and any changes and modifications made within the scope of the patent application of the present embodiment should be included in the scope of the present embodiment.
