Description

Technical Field

[0001] This utility model belongs to the field of paperboard trimming technology, and in particular relates to an adjustable honeycomb paperboard trimming mechanism. Background Technology

[0002] Honeycomb cardboard has advantages such as being lightweight, high-strength, and environmentally friendly, and is widely used in the transport packaging of electronic products, home appliances, and other products. During the production process, problems such as burrs and unevenness may occur on the edges of the honeycomb cardboard, requiring edge trimming by a trimming mechanism. Currently, existing trimming mechanisms typically operate in a one-way "push-cut" mode, pushing the cardboard along a straight line to the trimming area before cutting and trimming to complete a single operation. However, in practical applications, operator misjudgment can easily lead to excessive (e.g., exceeding the cutting area) or insufficient (not fully reaching the cutting position) pushing of the cardboard. Excessive pushing will directly cause the trimming depth to exceed the standard, damaging the structural strength of the cardboard and even generating waste; insufficient pushing will result in incomplete trimming, leaving residual burrs that require rework, severely impacting production efficiency.

[0003] To address the aforementioned issues, this application proposes an adjustable honeycomb paperboard trimming mechanism. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable honeycomb paperboard trimming mechanism, which solves the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is an adjustable honeycomb cardboard trimming mechanism, including a base parallel to the horizontal plane and a trimming knife above it, as well as two side clamping plates symmetrically arranged above a placement seat fixed on the top surface of the base. Two translation plates are symmetrically arranged in a cavity I within the placement seat. A connecting plate is fixed to the side of each translation plate I, penetrating the side wall of the placement seat. A connecting arm is fixed to the side wall of each side clamping plate and connected to the connecting plate I. The two translation plates I respectively drive the two side clamping plates to translate. A baffle is arranged above the placement seat. A translation plate II, perpendicular to the translation plates I, is arranged in a cavity II within the placement seat. A connecting plate II, penetrating the side wall of the placement seat, is located on one side of each translation plate II. A connecting arm is fixed to the side wall of the baffle and connected to the connecting plate II. The translation plate II is used to drive the baffle to translate.

[0006] Furthermore, the top surface of the placement seat is provided with a groove for cooperating with the trimming knife, and the top surface of the placement seat is provided with a push plate, with the baffle and the push plate located on both sides of the groove.

[0007] Furthermore, two translation blocks are symmetrically arranged inside the cavity, and a bidirectional screw rod threadedly connected to the translation blocks is rotatably installed inside the cavity. A guide rod is fixed inside the cavity and slidably connected to the translation blocks. The translation blocks and the translation plate are respectively hinged to the two ends of the connecting rod through fixed hinge seats. A motor with its output end fixedly connected to the bidirectional screw rod is fixed on the outer wall of the placement seat.

[0008] Furthermore, a screw rod that is threadedly connected to the translation plate is rotatably installed inside the cavity two, a motor two whose output end is fixedly connected to the screw rod is fixedly installed on the outer wall of the placement seat, and a guide rod two that is slidably connected to the translation plate two is fixedly installed inside the cavity two.

[0009] Furthermore, the push plate is fixedly connected to the output end of the electric push rod, the electric push rod is fixedly mounted on one side of the fixed plate, and the fixed plate is fixedly connected to the top surface of the placement seat.

[0010] Furthermore, a gantry frame is fixedly mounted on the top surface of the base, and an electric push rod 2 with its output end fixedly connected to the trimming knife is fixedly mounted on the top surface of the gantry frame.

[0011] Furthermore, a limiting block is fixed on the top surface of the base, and the distance between the limiting blocks is greater than the length of the knife groove. The limiting block is used to block the baffle.

[0012] This utility model has the following beneficial effects: This utility model uses side clamping plates to clamp and fix the cardboard on both sides, which are symmetrically arranged on the top surface of the placement seat. The two side clamping plates cooperate with the translation plate, connecting plate and connecting arm in the cavity to realize the synchronous translation of the two clamping plates and ensure the uniformity of the clamping force on both sides. This invention limits the baffle by contacting the trimming end of the cardboard to be trimmed, thus preventing the cardboard from being pushed too far or too far. This solves the trimming quality problem caused by stroke control deviation in the traditional "push-cut" mode.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0018] Please see Figure 1 - Figure 4As shown, this utility model is an adjustable honeycomb cardboard trimming mechanism, including a base 1 parallel to the horizontal plane and a trimming knife 17 above it, and two side clamping plates 3, symmetrically arranged above a placement seat 2 fixed on the top surface of the base 1. Two translation plates 4 are symmetrically arranged in a cavity 201 opened in the placement seat 2. A connecting plate 5 is fixedly provided on the side of the translation plate 4, penetrating the side wall of the placement seat 2. A connecting arm 301 fixedly connected to the connecting plate 5 is fixedly provided on the side wall of the side clamping plate 3. The two translation plates 4 respectively drive the two side clamping plates 3 to translate. A baffle 9 is arranged above the placement seat 2. A translation plate 11 perpendicular to the translation plate 4 is provided in a cavity 202 opened in the placement seat 2. A connecting plate 10 penetrating the side wall of the placement seat 2 is provided on one side of the translation plate 11. A connecting arm 901 fixedly connected to the connecting plate 10 is fixedly provided on the side wall of the baffle 9. The translation plate 11 is used to drive the baffle 9 to translate. This embodiment provides an adjustable honeycomb paperboard trimming mechanism. The second translation plate 11 moves within the second cavity 202, driving the baffle 9 to move horizontally via the second connecting plate 10 and the second connecting arm 901. After adjusting the position of the baffle 9 and placing the paperboard on the placement seat 2, the end of the paperboard to be trimmed is aligned with the baffle 9. The paperboard is pushed so that the end to be trimmed abuts against the baffle 9, limiting the paperboard and preventing excessive movement. Then, the two translation plates 4 move within the first cavity 201 respectively, driving the clamping plates 3 on both sides to move closer to the sides of the paperboard via the first connecting plate 5 and the first connecting arm 301 to clamp and fix the paperboard, preventing the paperboard from shifting during the trimming process.

[0019] The top surface of the placement seat 2 is provided with a knife groove 203 that cooperates with the trimming knife 17. The top surface of the placement seat 2 is provided with a push plate 13. The baffle 9 and the push plate 13 are located on both sides of the knife groove 203. The push plate 13 is used to push the cardboard so that the cardboard abuts against the baffle 9, and can also form a lateral restriction on the cardboard.

[0020] The cavity 201 contains two symmetrically arranged translation blocks 7, and a bidirectional screw 8 threadedly connected to the translation blocks 7 is rotatably installed in the cavity 201. A guide rod 2011 slidably connected to the translation blocks 7 is fixed in the cavity 201. The translation blocks 7 and the translation plate 4 are respectively hinged to both ends of the connecting rod 6 through fixed hinge seats. The outer wall of the placement seat 2 is fixed with a motor 801 whose output end is fixed to the bidirectional screw 8. The motor 801 is used to drive the bidirectional screw 8 to rotate, further driving the two translation blocks 7 to move in opposite directions. Then, the connecting rod 6 drives the translation plate 4 to move, thereby driving the translation plate 4 to translate through the connecting plate 5 and the connecting arm 301, so that the two translation plates 4 move closer or further away from each other. The guide rod 2011 is used to guide the translation blocks 7 to prevent the translation blocks 7 from shifting with the rotation of the bidirectional screw 8. The translation plate 4 can also prevent the connecting plate 5 from moving outward too much and separating from the placement seat 2.

[0021] The cavity 202 contains a screw 12 threadedly connected to the translation plate 11. The outer wall of the placement seat 2 is fixed with a motor 1201 whose output end is fixedly connected to the screw 12. The cavity 202 contains a guide rod 2021 slidably connected to the translation plate 11. The motor 1201 drives the screw 12 to rotate, which in turn drives the translation plate 11 to move. This, in turn, drives the baffle 9 to move through the connecting plate 10 and the connecting arm 901, thereby adjusting the position of the baffle 9 and controlling the trimming length of the cardboard. The guide rod 2021 guides the translation plate 11 to prevent it from shifting when the screw 12 rotates.

[0022] The push plate 13 is fixedly connected to the output end of the electric push rod 14. The electric push rod 14 is fixed on one side of the fixed plate 1401, and the fixed plate 1401 is fixedly connected to the top surface of the placement seat 2. After the cardboard is placed on the placement seat 2, the electric push rod 14 drives the push plate 13 to move horizontally, thereby causing the cardboard to come into contact with the baffle 9.

[0023] The base 1 has a gantry frame 15 fixedly mounted on its top surface, and the gantry frame 15 has an electric push rod 16 with its output end fixedly connected to the trimming knife 17. The electric push rod 16 is used to drive the trimming knife 17 to vertically lift and lower to trim and cut the cardboard.

[0024] The base 1 has a limiting block 18 fixed on its top surface, and the distance between the limiting blocks 18 is greater than the length of the knife groove 203. The limiting block 18 is used to block the baffle 9 to prevent it from blocking the knife groove 203. The limiting block 18 is used to block the baffle 9 from moving excessively, to prevent the baffle 9 from blocking the knife groove 203 and affecting the trimming operation, and at the same time to protect the mechanism from mechanical interference.

[0025] It is understandable that this utility model can limit the cardboard to prevent it from moving excessively, control the width of the cardboard trimming according to needs, and clamp and fix the cardboard to prevent it from shifting when the cardboard is cut.

[0026] A specific application of the operation process of this embodiment is as follows: Adjust the position of the baffle 9 according to the trimming width requirement. During adjustment, start the motor 1201 to drive the screw 12 to rotate, and further adjust the position of the baffle 9 by moving the baffle 9 through the translation plate 11, the connecting plate 10 and the connecting arm 901. Place the cardboard on the placement seat 2. Use the electric push rod 14 to extend the push plate 13 and push the cardboard to contact the baffle 9. Then drive the motor 801 to rotate the bidirectional screw 8. Further, through the translation block 7, connecting rod 6, translation plate 4, connecting plate 5 and connecting arm 301, the side clamping plates 3 move closer to each other, so that the side clamping plates 3 clamp and fix the cardboard on both sides. Finally, the electric push rod 16 moves the trimming knife 17 vertically downward to cut and trim the cardboard.
