Description

Technical Field

[0001] The utility model relates to the technical field of carton processing, and relates to an indentation device for carton processing. Background Technique

[0002] Carton processing includes many steps, including indentation of the cardboard used to make the carton. The function of this indentation is to facilitate the cutting and positioning in the subsequent processes of the cardboard and to facilitate the subsequent folding of the cardboard into a box;

[0003] When performing the indentation operation on the cardboard, an indentation device is generally used. Since the cardboard itself has elasticity, when the cardboard is squeezed, the squeezed position deforms. When not squeezed, the cardboard may partially rebound by virtue of its own elasticity, resulting in insufficient depth of the indentation on the cardboard. As a result, there is uncertainty in the bending position of the cardboard due to too shallow indentation, and the carton is likely to break during transportation or storage, which may cause leakage or damage to the internal items;

[0004] To solve the above problems, an indentation device for carton processing is proposed in this application. Utility Model Content

[0005] The utility model aims at the technical problems existing in the prior art, and provides an indentation device for carton processing.

[0006] The technical solution for the utility model to solve the above technical problems is as follows: An indentation device for carton processing, including a placement table, an electric telescopic rod is arranged above the placement table, an installation frame is installed at the telescopic end of the electric telescopic rod, an indentation inspection structure is arranged on the installation frame, and a pressing plate is arranged on the installation frame through the indentation inspection structure;

[0007] The indentation inspection structure includes an installation shell detachably installed on the installation frame and a slider installed on the pressing plate. A chute is opened on the inner wall of the installation shell, the pressing plate is movably inserted into the installation shell, and the slider is slidably connected to the installation shell through the chute;

[0008] A pressing groove block is adjustably installed on the placement table, a pressing groove is opened on the pressing groove block, and the bottom of the pressing plate is adapted to the pressing groove;

[0009] The installation shell is adjustably provided with an adjusting block through one of the chutes. The adjusting block is located below the slider. A contact switch is installed on the top of the adjusting block. A timing switch controller is installed on the installation shell. The contact switch is electrically connected to the timing switch controller and the electric telescopic rod;

[0010] An adjusting structure is arranged on the placement table for adjusting the height of the pressing groove block.

[0011] A bracket is installed on the placement table, and the electric telescopic rod is installed on the bracket. By setting the bracket, it is used to support the electric telescopic rod.

[0012] Screws are installed on the mounting frame, and the mounting shell is installed on the mounting frame by using the screws. By setting the screws, it is convenient to disassemble and assemble the mounting shell.

[0013] A first threaded rod is rotatably connected to the mounting shell. The outer side of the first threaded rod is threadedly connected through the inner wall of the adjusting block. A through hole is penetrated and opened on the slider located directly above the adjusting block. The first threaded rod is movably inserted into the slider through the through hole. By setting the first threaded rod and the through hole, it is convenient to limit the moving distance of the pressing plate.

[0014] A first rotating block is installed at the bottom end of the first threaded rod. By setting the first rotating block, it is convenient to rotate the first threaded rod.

[0015] The adjusting structure includes an adjusting groove opened on the placement table and an operation opening penetrated through the placement table. A second threaded rod is rotatably connected to the placement table. The pressing groove block is slidably connected to the placement table through the adjusting groove. The outer side of the top end of the second threaded rod is threadedly connected to the inner wall of the pressing groove block. By setting the adjusting structure, it is convenient to adjust the height of the indentation block.

[0016] A second rotating block is installed at the bottom end of the second threaded rod. The second rotating block is located within the operation opening. By setting the second rotating block, it is convenient to rotate the second threaded rod.

[0017] A bearing is installed on the inner wall of the placement table. The outer side of the second threaded rod is connected to the inner ring of the bearing. By setting the bearing, it is used to support and assist the rotation of the second threaded rod.

[0018] The beneficial effects of the present utility model are:

[0019] If the depth of the indentation on the cardboard is insufficient, during the initial upward movement of the mounting shell, the pressing plate will also be lifted by the cardboard and move upward. By setting the indentation inspection structure, the slider touches the contact switch longer than expected time. The timing switch controller compares this time value with the pre-set time, thereby controlling the electric telescopic rod to drive the pressing plate to move downward again to press the cardboard again until the depth of the indentation on the cardboard is sufficient, thus achieving the effect of ensuring the depth of the indentation on the cardboard as much as possible, and avoiding as much as possible the uncertainty of the bending position of the cardboard due to too shallow indentation and the possibility of the cardboard box being easily broken during transportation or storage, which may cause leakage or damage of the internal items;

[0020] By rotating the first rotating block, the first threaded rod is driven to rotate. The rotation of the first threaded rod drives the movement of the adjusting block, which is used to adjust the distance between the slider and the adjusting block according to the requirements of different indentation depths, achieving the purpose of matching the time required to touch the contact switch for different indentation depth requirements;

[0021] By setting the adjusting structure and rotating the second rotating block, the upward or downward movement of the indentation groove block is driven, achieving the purpose of moving the indentation groove upward or downward, and is used to make the depth of the indentation groove match the required indentation depth of the cardboard by coordinating with the depth of the adjusting groove.

Any embodiment described as "for example" in the present application is not necessarily construed as being more preferred or having more advantages than other embodiments. In order for any person skilled in the art to implement and use the present utility model, the following description is given. In the following description, details are set forth for purposes of explanation. It should be understood that those of ordinary skill in the art can recognize that the present utility model can be implemented without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid unnecessary details from obscuring the description of the present utility model. Therefore, the present utility model is not intended to be limited to the embodiments shown, but is consistent with the broadest scope that conforms to the principles and features disclosed in the present application.

[0038] Refer to Figure 1 , an indentation device for carton processing, including a placement table 1. Above the placement table 1, an electric telescopic rod 3 is provided. The telescopic end of the electric telescopic rod 3 is installed with a mounting frame 4. On the mounting frame 4, an indentation inspection structure 6 is provided. Through the indentation inspection structure 6, a pressing plate 5 is provided on the mounting frame 4. On the placement table 1, an indentation block 7 is adjustably installed. An indentation groove 701 is provided on the indentation block 7. The bottom of the pressing plate 5 is adapted to the indentation groove 701. Place the cardboard on the placement table 1, and then start the electric telescopic rod 3 to drive the mounting frame 4 to move downward with its telescopic end. The downward movement of the mounting frame 4 drives the downward movement of the pressing plate 5, so that the pressing plate 5 presses the cardboard, causing the deformed area of the cardboard to deform into the indentation groove 701 to complete the indentation process of the cardboard.

[0039] A bracket 2 is installed on the placement table 1, and the electric telescopic rod 3 is installed on the bracket 2. The bracket 2 is used to support the electric telescopic rod 3.

[0040] Refer to Figure 1-3, the indentation inspection structure 6 includes a mounting shell 601 detachably mounted on the mounting frame 4 and a slider 603 mounted on the pressing plate 5. A chute 602 is formed on the inner wall of the mounting shell 601. The pressing plate 5 is movably inserted into the mounting shell 601. The slider 603 is slidably connected to the mounting shell 601 through the chute 602. The mounting shell 601 is provided with an adjusting block 607 through one of the chutes 602. The adjusting block 607 is located below the slider 603. A contact switch 608 is mounted on the top of the adjusting block 607. A timing switch controller 609 is mounted on the mounting shell 601. The contact switch 608 is electrically connected to the timing switch controller 609 and the electric telescopic rod 3. First of all, it should be determined that the vertical distance in the chute 602 is the same as the depth of the indentation required for the cardboard. Specifically, the upward or downward movement distance that the pressing plate 5 can perform in the mounting shell 601 is the same as the depth of the indentation required for the cardboard. Therefore, it is necessary to preset the time when the slider 603 touches the contact switch 608 in the state of normal indentation depth on the timing switch controller 609, and the timing switch controller 609 starts timing when the telescopic end of the electric telescopic rod 3 drives the mounting shell 601 to move upward;

[0041] According to the above technical solution, specifically, when the telescopic end of the electric telescopic rod 3 drives the mounting shell 601 to move downward, the mounting shell 601 drives the pressing plate 5 to move downward accordingly. When the pressing plate 5 touches the cardboard, the pressing plate 5 stops moving downward. At this time, the mounting shell 601 continues to move downward. Relative to the downward movement of the mounting shell 601, the slider 603 moves upward in the chute 602 and finally contacts the top inner wall of the chute 602. At this time, the mounting shell 601 drives the pressing plate 5 to move downward to press the cardboard, thereby forming an indentation on the cardboard. After the pressing plate 5 completes an indentation operation, the telescopic end of the electric telescopic rod 3 drives the mounting shell 601 to move upward. If the depth of the indentation on the cardboard is insufficient, during the upward movement of the mounting shell 601, the pressing plate 5 will also be lifted upward by the cardboard, so that the slider 603 touches the contact switch 608 longer than expected. At this time, the contact switch 608 sends a signal to the timing switch controller 609. After receiving the signal, the timing switch controller 609 compares the time value with the preset time, thereby controlling the electric telescopic rod 3 to drive the pressing plate 5 to move downward again to press the cardboard again until the depth of the indentation on the cardboard is sufficient, thereby achieving the effect of ensuring the depth of the indentation on the cardboard as much as possible.

[0042] Among them, the specific model of the timing switch controller 609 is the KG316T time control switch produced by Wenzhou Meidelibang Electric Co., Ltd. The specific model of the contact switch 608 is TS-1187. The circuit connection method of the contact switch 608, the timing switch controller 609 and the electric telescopic rod 3 can be reasonably set according to the actual situation, and the signal transmission method of the three is the prior art;

[0043] In addition, it should be noted that the timing switch controller 609 is used to set the preview value and compare the time value required for the comparison slider 603 to touch the contact switch 608 with the preset time. The timing switch controller 609 is electrically connected to the computer, and the preset on the timing switch controller 609 is set using the computer.

[0044] Refer to Figure 1 , screws 401 are installed on the mounting bracket 4, and the mounting shell 601 is installed on the mounting bracket 4 using the screws 401. The screws 401 facilitate the disassembly and assembly of the mounting shell 601.

[0045] Refer to Figure 2 and Figure 3 , a first threaded rod 605 is rotatably connected to the mounting shell 601. The outer side of the first threaded rod 605 is threadedly connected through the inner wall of the adjusting block 607. A through hole 604 is formed through the slider 603 directly above the adjusting block 607. The first threaded rod 605 is movably inserted into the slider 603 through the through hole 604. A first rotating block 606 is installed at the bottom end of the first threaded rod 605. By rotating the first rotating block 606, the first threaded rod 605 is driven to rotate. The rotation of the first threaded rod 605 drives the movement of the adjusting block 607, achieving the effect of adjusting the distance between the slider 603 and the adjusting block 607 according to the requirements of different indentation depths, and realizing the purpose of matching the time required to touch the contact switch 608 for different indentation depth requirements.

[0046] Refer to Figure 4 , an adjusting structure 8 is provided on the placing table 1 for adjusting the height of the grooving block 7. The adjusting structure 8 includes an adjusting groove 801 formed in the placing table 1 and an operation opening 802 formed through the placing table 1. A second threaded rod 804 is rotatably connected to the placing table 1. The grooving block 7 is slidably connected to the placing table 1 through the adjusting groove 801. The outer side of the top end of the second threaded rod 804 is threadedly connected to the inner wall of the grooving block 7. A second rotating block 805 is installed at the bottom end of the second threaded rod 804. The second rotating block 805 is located within the operation opening 802. By rotating the second rotating block 805, the second threaded rod 804 is driven to rotate. The rotation of the second threaded rod 804 drives the grooving block 7 to move up or down, achieving the purpose of moving the indentation groove 701 up or down, and is used to make the depth of the indentation groove 701 match the required indentation depth of the cardboard in cooperation with the adjusting groove 801.

[0047] A bearing 803 is installed on the inner wall of the placing table 1. The outer side of the second threaded rod 804 is connected to the inner ring of the bearing 803. The bearing 803 is used to support and assist the rotation of the second threaded rod 804.

[0048] Working principle:

[0049] For the indentation device used for carton processing, when the telescopic end of the electric telescopic rod 3 drives the mounting shell 601 to move downward, the mounting shell 601 drives the pressing plate 5 to move downward accordingly. When the pressing plate 5 touches the cardboard, the pressing plate 5 stops moving downward. At this time, the mounting shell 601 continues to move downward. Relative to the downward movement of the mounting shell 601, the slider 603 moves upward in the chute 602 and finally contacts the top inner wall of the chute 602. At this time, the mounting shell 601 drives the pressing plate 5 to move downward to press the cardboard, thereby forming an indentation on the cardboard. After the pressing plate 5 completes one indentation operation, the telescopic end of the electric telescopic rod 3 drives the mounting shell 601 to move upward. If the depth of the indentation on the cardboard is insufficient, during the upward movement of the mounting shell 601, the pressing plate 5 will also be pushed up by the cardboard to move upward, so that the slider 603 touches the contact switch 608 longer than expected. At this time, the contact switch 608 sends a signal to the timing switch controller 609. After receiving the signal, the timing switch controller 609 compares this time value with the preset time, thereby controlling the electric telescopic rod 3 to drive the pressing plate 5 to move downward again to press the cardboard again until the depth of the indentation on the cardboard is sufficient, thus achieving the effect of ensuring the depth of the indentation on the cardboard as much as possible.

[0050] For the indentation device used for carton processing, by rotating the first rotating block 606, it drives the first threaded rod 605 to rotate. The rotation of the first threaded rod 605 drives the movement of the adjusting block 607, achieving the effect of adjusting the distance between the slider 603 and the adjusting block 607 according to the requirements of different indentation depths, and realizing the purpose of matching the time required to touch the contact switch 608 for different indentation depth requirements.

[0051] For the indentation device used for carton processing, by rotating the second rotating block 805, it drives the second threaded rod 804 to rotate. The rotation of the second threaded rod 804 drives the upward or downward movement of the indentation groove block 7, achieving the purpose of moving the indentation groove 701 upward or downward, and is used to make the depth of the indentation groove 701 match the required indentation depth of the cardboard in cooperation with the adjusting groove 801.

[0052] Although the preferred embodiments of the present invention have been described, those skilled in the art can make additional changes and modifications to these embodiments once they know the basic creative concept. Therefore, the appended claims are intended to be construed to include the preferred embodiments and all changes and modifications falling within the scope of the present invention.

[0053] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these modifications and variations.
