Description

Technical Field

[0001] This invention belongs to the field of packaging manufacturing technology, specifically relating to a device and method for assembling card cutters. Background Technology

[0002] Paper cutter cards, as the name suggests, are cardboard dividers made through a die-cutting process. They are used to separate items inside cartons, preventing collisions and shifting. They effectively separate different items, avoiding friction and shaking, and are especially suitable for protecting delicate small items (such as circuit boards, mobile phone accessories, etc.) during transport. Paper cutter cards are a common packaging material processing tool, mainly used to cut large sheets of kraft paper or corrugated paper into the required size and shape. Cardboard cutter cards are tools used to separate and secure items inside cartons. In terms of technical characteristics, they possess a certain degree of flexibility and strength, allowing them to be inserted into the carton while maintaining a stable shape within the box. Structurally, they typically consist of a cutter plate and slots, with the shape and size of the cutter plate designed according to actual needs. In terms of specifications, various sizes are available to fit different sized cartons and items.

[0003] However, the current assembly technology for the cutting tools is immature, and they are often manually placed into their corresponding slots according to design requirements. During insertion, it is necessary to ensure that the slots of the first cutting tool are aligned with the slots of the second cutting tool, that the first and second cutting tools are perpendicular to each other, and that the insertion force is moderate to avoid damage to the cutting tools or insecure insertion, which may lead to component deformation or loose connection, increasing the assembly difficulty, and the assembly process is inefficient.

The lifting assembly 5 has a raised state and a lowered state. When the lifting assembly 5 is in the raised state, the upper tool holder assembly 1 and the lower tool holder assembly 2 are far apart. When the lifting assembly 5 is in the lowered state, the upper tool holder assembly 1 and the lower tool holder assembly 2 are close together.

[0025] The tool holder assembly device of this embodiment has a reasonable structural design. It can achieve the mutual assembly of two tool holders by fixing and displacing them, without the need for manual pressing of the tool holders. In addition, the size of the fixing space of the tool holder fixing component 3 is adjustable, so it can meet the assembly of most sizes of tool holders. It is not unsuitable due to different design dimensions between tool holder slots, and has a wide range of applications. The fixed potential energy compression mechanism and the pull rod potential energy compression mechanism facilitate the installation and disassembly of the tool holders, making it easy to operate.

[0026] The specific structure of the blade holder fixing component 3 in this embodiment is as follows: It includes a first blade fixing plate 301, a second blade fixing plate 302, and a blade clamping spring 303; A fixed space is formed between the first blade fixing plate 301 and the second blade fixing plate 302. The blade clamping spring 303 is a fixed potential energy compression mechanism, and the blade clamping spring 303 is connected to the first blade fixing plate 301 and the second blade fixing plate 302 respectively.

[0027] Specifically, the first blade fixing plate 301 has fixing seats 304 at both ends, and the fixing seats 304 are provided with first bolts 104. The fixing seats 304 are connected to the upper blade clamping assembly 1 and the lower blade clamping assembly 2 through the first bolts 104. The second blade fixing plate 302 is connected to the pull rod mechanism of the pull rod assembly 4.

[0028] In the structure of the blade clamping assembly 3 described above, the first blade clamping plate 301 and the second blade clamping plate 302 are in a state of being far apart, that is, the clamping space is in a fixed and released state, and the blade clamping spring 303 is in a natural state, while the clamping potential energy compression mechanism is in a fixed potential energy release state; the first blade clamping plate 301 and the second blade clamping plate 302 are in a state of being close together, that is, the clamping space is in a fixed and clamped state, and the blade clamping spring 303 is in a compressed state, while the clamping potential energy compression mechanism is in a fixed potential energy compression state.

[0029] The specific structure of the pull rod assembly 4 in this embodiment is as follows: It includes a pull rod 401, a pull rod adjusting spring 402, and a buckle 403; The pull rod 401 is slidably engaged with the upper blade clamping assembly 1 and the lower blade clamping assembly 2. The buckle 403 is provided on the pull rod 401 and forms a pull rod mechanism with the pull rod 401. The pull rod adjusting spring 402 is the pull rod potential energy compression mechanism of the pull rod assembly 4. One end of the pull rod adjusting spring 402 is connected to the pull rod 401, and the other end is connected to the upper blade clamping assembly 1 and the lower blade clamping assembly 2. The buckle 403 abuts against the second blade fixing plate 302.

[0030] Specifically, a number of fixing holes 4011 are provided on the outer wall surface of the tie rod 401 along its length extension direction, and the buckle 403 is provided with a fixing member that cooperates with the fixing holes 4011.

[0031] The buckle 403 is positioned and engaged with the fixing holes 4011 at different positions according to the position of the blade clamping assembly 3. During the sliding process of the pull rod 401 with the upper blade clamping assembly 1 and the lower blade clamping assembly 2, the state of the pull rod adjusting spring 402 can make the pull rod potential energy compression mechanism be in the pull rod potential energy extension state and the pull rod potential energy compression state. Specifically, when the first blade fixing plate 301 and the second blade fixing plate 302 are far apart, the pull rod adjusting spring 402 is in the first extension state and the pull rod potential energy compression mechanism is in the pull rod potential energy extension state. When the first blade fixing plate 301 and the second blade fixing plate 302 are close together, the pull rod adjusting spring 402 is in the second extension state and the pull rod potential energy compression mechanism is in the pull rod potential energy compression state. Under the elastic force of the pull rod adjusting spring 402, the buckle 403 moves the second blade fixing plate 302.

[0032] In this embodiment, the upper knife clamp assembly 1 and the lower knife clamp assembly 2 have the same structure. In this embodiment, the number of knife clamp fixing components 3 on the upper knife clamp assembly 1 and the lower knife clamp assembly 2 is more than two and arranged in parallel with each other.

[0033] The specific structure of the upper blade card assembly 1 in this embodiment is as follows: It includes a steel base 101, on which a sliding groove 102 is provided for sliding engagement of a tie rod 401. The steel base 101 is provided with a plurality of first bolt holes 103 along the length extension direction of the sliding groove 102. A first bolt 104 engages with one of the first bolt holes 103 and is connected to a fixed seat 304. The pull rod adjusting spring 402 is located in the slide groove 102. One end of the pull rod 401 is connected to the pull rod adjusting spring 402, and the other end is provided with a handle 404. The handle allows the user to easily move the pull rod 401 within the slide groove 102.

[0034] Meanwhile, the first bolt hole 103 and its arrangement position can make the first blade fixing plate 301 arranged and fixed along the length extension direction of the slide groove 102.

[0035] Specifically, scale lines are provided on the steel base 101 along the length of the slide groove 102.

[0036] The aforementioned scale lines can accurately determine and position the first blade fixing plate 301 on the steel base 101.

[0037] The lifting assembly 5 in this embodiment includes a lifting drive device and a lifting arm mechanism. The two ends of the lifting arm mechanism are respectively connected to the upper knife clamp assembly 1 and the lower knife clamp assembly 2. The driving end of the lifting drive device is connected to the lifting arm mechanism and can cause the lifting arm mechanism to be in an extended state and a retracted state. The lifting arm mechanism includes several lifting rods, which are hinged together and connected in a cross shape.

[0038] The lifting drive device in this embodiment can be a hydraulic or pneumatic device to drive the lifting arm mechanism.

[0039] Specifically, the length extension direction of the fixing space portion of the upper knife clamp assembly 1 is perpendicular to the length extension direction of the fixing space portion of the lower knife clamp assembly 2.

[0040] The present invention also includes a blade card assembly method, which is accomplished by the blade card assembly device described above. The steps of the blade card assembly method are as follows: S1. The lifting component 5 is in the raised state, so that the upper tool holder component 1 and the lower tool holder component 2 are far apart; S2. The operator fixes the first tool holder 6 to the tool holder fixing component 3 of the upper tool holder assembly 1: The lever mechanism is set to the lever release state, and the lever potential energy compression mechanism is set to the lever potential energy extension state, thereby setting the fixed potential energy compression mechanism to the fixed potential energy release state and the fixed space to the fixed release state. Then, the first tool holder 6 is placed in the fixed space, and the lever mechanism is set to the lever lock state, and the lever potential energy compression mechanism is set to the lever potential energy compression state, setting the fixed potential energy compression mechanism to the fixed potential energy compression state, setting the fixed space to the fixed clamping state, and clamping the first tool holder 6. The operator fixes the second tool holder 7 to the tool holder fixing component 3 of the lower tool holder assembly 2. The operation method is the same as the above-mentioned fixing of the first tool holder 6 to the tool holder fixing component 3 of the upper tool holder assembly 1. It should be noted that the first knife card 6 and the second knife card 7 are provided with slots. Therefore, when the first knife card 6 is fixed to the knife card fixing component 3 of the upper knife card assembly 1, and the second knife card is fixed to the knife card fixing component 3 of the lower knife card assembly 2, it is necessary to ensure that the slot of the first knife card 6 corresponds to the slot of the second knife card 7. S3. By lowering the lifting assembly 5, the upper tool holder assembly 1 and the lower tool holder assembly 2 are brought closer together, and the first tool holder 6 and the second tool holder 7 are engaged. Specifically, the first tool holder 6 and the second tool holder 7 are provided with slots. Therefore, the length extension direction of the fixing space of the tool holder fixing assembly 3 of the upper tool holder assembly 1 is perpendicular to the length extension direction of the fixing space of the tool holder fixing assembly 3 of the lower tool holder assembly 2, ensuring that the first tool holder 6 and the second tool holder 7 are perpendicular and that their slots are engaged. S4. Separate the first cutter card 6 from the cutter card fixing component 3 of the upper cutter card assembly 1, and then raise the upper cutter card assembly 1 and the lower cutter card assembly 2 by means of the lifting component 5, so that the upper cutter card assembly 1 and the lower cutter card assembly 2 are separated. Then separate the second cutter card 7 from the cutter card fixing component 3 of the lower cutter card assembly 2, and finally remove the first cutter card 6 and the second cutter card 7.

[0041] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
