Description
Technical Field
[0001] This invention relates to the field of tape processing, and more specifically to a tape processing die-cutting device. Background Technology
[0002] Die-cutting is the most common process used in packaging tape. It involves using a die-cutting knife to cut the tape into the required shape according to the product design requirements and under pressure.
[0003] However, it is too costly to make separate molds for small-batch, multi-type tape die-cutting. At the same time, the molds are inconvenient to install, and the efficiency is low when the cutter needs to be changed for different types of tape. In addition, tape is usually packaged in rolls, and warping and misalignment may occur during processing, which affects the die-cutting quality. Furthermore, tape is easy to stick to the die-cutting cutter during the die-cutting process, resulting in waste.
[0004] Therefore, it is necessary to provide tape processing and die-cutting equipment to solve the problems mentioned in the background art. Summary of the Invention
[0005] To achieve the above objectives, the present invention provides the following technical solution: a tape processing and die-cutting device, comprising:
[0006] Bottom ring;
[0007] The transmission components are arranged in multiple groups evenly around the circumference, with one end of each component fixed to the bottom ring.
[0008] A support plate is fixed to the other end of the transmission component;

[0019] The transmission platform is arranged in multiple circular positions within a fixed groove on the central axis, and multiple fixing pins are provided between the transmission platform and the fixed groove.
[0020] Furthermore, as a preferred embodiment, the hinge frame has a built-in spring, which allows the main drive wheel and the auxiliary drive wheel to fit against the transmission table. The auxiliary drive wheel is rigid with a surface roughness of Ra3.2, providing a rolling resistance in the range of 0.5-0.8N. The surface of the main drive wheel is made of rubber. Multiple positioning slots can be opened on the exposed surface of the transmission table to install positioning plates, and the width of the middle slot can be adjusted within the range of 20-60mm.
[0021] Furthermore, preferably, the die-cutting assembly includes:
[0022] The control console is fixed inside the support plate and contains multiple sets of motors.
[0023] The power input is connected to the control console at one end and to the power source at the other end.
[0024] The housing is fixed to the bottom of the console;
[0025] The slitting components are arranged in multiple vertically sliding configurations within the housing;
[0026] A directional tie rod, disposed within the housing, is driven by a motor within the control console and engages with the cutting assembly; and
[0027] The adjustable screw is rotatably mounted inside the housing and is driven by a motor inside the control console.
[0028] Furthermore, as a preferred embodiment, the adjusting screw engages with the slitting assembly via a thread to control the up-and-down movement of the slitting assembly, adjusting the distance between the bottom end of the slitting assembly and the bottom end of the housing, with an adjustment range of 0-10mm. The orientation of the slitting assembly is simultaneously adjusted by the directional adjustment rod, and a mounting groove is provided at the bottom of the housing for placing the slitting assembly.
[0029] Furthermore, preferably, the slitting component includes:
[0030] The spacing threaded sleeve is slidably disposed inside the control console, and an annular groove is formed on its outer circumferential surface;
[0031] The directional screw is coaxially rotatably disposed inside the spacing threaded sleeve, and the circumferential surface near one end is machined with teeth;
[0032] A swivel ring is rotatably disposed between the directional screw and the spacing threaded sleeve;
[0033] The die-cutting tool is fixed at the other end of the directional screw;
[0034] An auxiliary pressure bar is slidably mounted on the die-cutting cutter; and

[0036] Furthermore, as a preferred embodiment, the die-cutting blade is generally semi-circular, and the cut is processed according to the die-cutting shape; the lower end of the auxiliary pressure rod is made of rubber, and compressed gas is filled inside the die-cutting tool.
[0037] Compared with the prior art, the present invention provides a tape processing and die-cutting device, which has the following beneficial effects:
[0038] 1. In this invention, multiple sets of die-cutting components are arranged around the central axis, with no other components in the radial outward direction, avoiding interference with other components during loading and unloading, facilitating disassembly and replacement, effectively improving work efficiency for small-batch, multi-variety die-cutting needs. At the same time, the die-cutting components are arranged symmetrically, and the force is balanced when working under full load, improving the overall stability of the device.
[0039] 2. In this invention, the die-cutting section of the tape is located between the auxiliary drive wheel and the main drive wheel. Since the tape may warp or misalign during transport, affecting the die-cutting quality, the conveyor table limits the tape's position. The auxiliary drive wheel presses the tape flat at the input end. As the main drive wheel drives the tape to slide, the rolling resistance of the auxiliary drive wheel applies a tensile force to the tape, ensuring the flatness and tension of the die-cut section and guaranteeing processing quality.
[0040] 3. In this invention, as the die-cutting assembly slides radially inward, its force gradually decreases. The distance between the slitting assembly and the bottom of the housing is adjusted by the pitch screw, thereby limiting the overall stroke of the die-cutting assembly to meet the die-cutting force requirements of different types of tape. The die-cutting blade can be replaced with different shaped blades according to the die-cutting shape of the tape. The blade is divided into three parts, which facilitates the processing of the blade and reduces the processing difficulty. On the other hand, it facilitates the design of the cutting tools for positioning features, identification features, back cutting release paper, etc. At the same time, the segmented cutting of the cutting tool and the action of the auxiliary pressure rod prevent the tape from sticking to the die-cutting tool during the die-cutting process, thus avoiding the generation of waste.

[0047] Please see Figure 1 In this embodiment of the invention, the tape processing and die-cutting device includes:
[0048] Bottom ring 1;
[0049] The transmission component 2 is arranged in multiple groups evenly around the circumference, with one end of each component fixed to the bottom ring 1.
[0050] Support plate 3 is fixed at the other end of the transmission component 2;
[0051] Multiple die-cutting components 4 are arranged and radially slidably disposed inside the transmission component 2;
[0052] The central shaft 5 is placed through the bottom ring 1 and the support plate 3;
[0053] Positioning bosses 6, arranged in multiple units, are evenly distributed and fixed to the outer surface of the central shaft 5; and
[0054] Multiple fixing plates 7 are arranged and fixed between the transmission components 2, and are in contact with the surface of the positioning boss 6.
[0055] In a preferred embodiment, the central shaft 5 has a fixing groove at the location corresponding to the transmission component 2.
[0056] It should be explained that by setting multiple sets of die-cutting components 4 arranged around the central axis 5, the tape is synchronously die-cut by an external pneumatic component (not shown in the figure). The stroke and die-cutting force are positively correlated. There are no other parts in the radial outward direction, which avoids interference with other parts during loading and unloading and facilitates disassembly and replacement. This effectively improves work efficiency for small-batch, multi-type die-cutting needs. At the same time, the die-cutting components 4 are arranged symmetrically, and the force is balanced when working under full load, which improves the overall stability of the device.
[0057] In this embodiment, as Figure 2 The transmission component 2 includes:
[0058] Support plate 21 is fixed between the bottom ring 1 and the support plate 3;
[0059] Two hinged frames 22 are arranged and hinged within the support plate 21;
[0060] The main drive wheel 23 is rotatably mounted on the hinge frame 22 and is connected to a drive motor 25;
[0061] The auxiliary drive wheel 24 is rotatably mounted on the hinge frame 22 and is positioned away from the main drive wheel 23 and close to the bottom ring 1; and the transmission platform 26 is arranged in multiple circumferentially and is located in the fixing groove of the central shaft 5, and multiple fixing pins 27 are provided between the transmission platform 26 and the fixing groove.
[0062] In a preferred embodiment, the hinge frame 22 has a built-in spring, which allows the main drive wheel 23 and the auxiliary drive wheel 24 to fit against the transmission table 26. The auxiliary drive wheel 24 is rigid with a surface roughness of Ra3.2, providing a rolling resistance in the range of 0.5-0.8N. The surface of the main drive wheel 23 is made of rubber. Multiple positioning slots can be opened on the exposed surface of the transmission table 26 to install positioning plates, and the width of the middle slot can be adjusted within the range of 20-60mm.
[0063] It should be explained that the positioning plate of the conveyor table 26 is pre-adjusted to the appropriate size according to the required die-cut tape size. The cut tape is placed with the release paper side attached to the conveyor table 26, and the main drive wheel 23 is clamped by the conveyor table 26 in conjunction with the contact surface. The tape is driven to slide from the auxiliary drive wheel 24 to the main drive wheel 23 by surface friction. The cutting is completed by adjusting the speed of the main drive wheel 23 in conjunction with the working frequency of the die-cutting assembly 4. The part of the tape to be die-cut is located between the auxiliary drive wheel 24 and the main drive wheel 23. Since the tape may warp or misalign during the transport process, affecting the die-cutting quality, the conveyor table 26 limits the tape. The auxiliary drive wheel 24 presses the tape flat at the input end. When the main drive wheel 23 drives the tape to slide, the rolling resistance of the auxiliary drive wheel 24 applies a tensile force to the tape, ensuring the flatness and tension of the tape in the die-cut section and ensuring the processing quality.
[0064] In this embodiment, as Figure 3 The die-cutting component 4 includes:
[0065] The control console 41 is fixed inside the support plate 21 and has multiple sets of motors installed inside.
[0066] Power inlet 42, one end is connected to the control console 41, and the other end is connected to the power supply;
[0067] Housing 43 is fixed to the bottom of the console 41;
[0068] The slitting components 44 are arranged in multiple vertically sliding configurations within the housing 43;
[0069] The directional tie rod 45 is disposed inside the housing 43, driven by a motor inside the control console 41, and meshes with the cutting assembly 44; and the pitch adjusting screw 46 is rotatably disposed inside the housing 43 and driven by a motor inside the control console 41.
[0070] In a preferred embodiment, the adjusting screw 46 engages with the slitting assembly 44 via a thread to control the up-and-down movement of the slitting assembly 44 and adjust the distance between the bottom end of the slitting assembly 44 and the bottom end of the housing 43. The adjustment range is 0-10mm. The orientation of the slitting assembly 44 is simultaneously adjusted by the directional pull rod 45. Meanwhile, the bottom of the housing 43 is provided with a mounting groove for placing the slitting assembly 44.
[0071] It should be explained that the slitting component 44 is detachable and replaceable. During the processing, the corresponding slitting component 44 needs to be placed in the mounting slot at the bottom of the housing 43 first. The spacing between the slitting components 44 is adjusted according to the tape die-cutting layout size and die-cutting size. During installation, micro-positioning is achieved through the threaded engagement of the adjusting screw 46. The circumferential direction of the slitting component 44 is adjusted synchronously through the directional pull rod 45 to change the tape cutting direction. As the die-cutting component 4 slides radially inward, its force gradually decreases. The distance between the slitting component 44 and the bottom of the housing 43 is adjusted by the adjusting screw 46, thereby limiting the overall stroke of the die-cutting component 4 to adapt to the die-cutting force requirements of different types of tape.
[0072] In this embodiment, as Figure 4 The slitting component 44 includes:
[0073] The spacing threaded sleeve 441 is slidably disposed inside the control console 41, and an annular groove 447 is provided on its outer circumferential surface;
[0074] The directional screw 442 is coaxially rotatably disposed inside the spacing threaded sleeve 441, and the circumferential surface near one end is machined with teeth.
[0075] The rotating ring 443 is rotatably disposed between the directional screw 442 and the spacing sleeve 441;
[0076] Die-cutting cutter 444 is fixed at the other end of the directional screw 442;
[0077] The auxiliary pressure rod 445 is slidably mounted on the die-cutting cutter 444; and
[0078] The die-cutting blade 446 is fixed at the lower end of the die-cutting tool 444.
[0079] In a preferred embodiment, the die-cutting blade 446 is generally semi-circular, and the cut is processed according to the die-cutting shape; the lower end of the auxiliary pressure rod 445 is made of rubber, and compressed gas is filled inside the die-cutting tool 444.
[0080] It should be explained that the die-cutting blade 446 can be replaced with different shaped blades according to the die-cutting shape of the tape, and the blade is divided into three parts. On the one hand, it facilitates the processing of the blade and reduces the processing difficulty. On the other hand, it facilitates the design of the tool for positioning features, identification features, back cutting release paper, etc. At the same time, with the tool split into sections for die-cutting and the action of the auxiliary pressure rod 445, the tape is prevented from sticking to the die-cutting tool 444 during the die-cutting process, thus avoiding the generation of waste.
[0081] In practical implementation, taking a 3M9888T tape with specifications of T0.15mm*1200mm*50m and a die-cutting shape of 30mm diameter circle with a die-cutting layout interval of 4mm as an example, first cut the tape into 25mm wide tapes, adjust the width between the positioning plates of the conveyor table 26 to 25mm, disassemble the die-cutting assembly 4 and install the slitting assembly 44 with an adjacent interval of 32mm, then adjust the circumferential direction of the slitting assembly 44 as a whole by adjusting the directional pull rod 45. Based on the selected tape material thickness of 0.15mm, no large die-cutting force is required. Adjust the distance from the slitting assembly 44 to the bottom of the housing 43 to 5mm by adjusting the pitch screw 46. Then, place the tape with the release paper side attached to the conveyor table 26, input from the auxiliary drive wheel 24 to the main drive wheel 23 output, start the machine, adjust the die-cutting frequency of the die-cutting assembly 4 and the speed of the drive motor 25 until the tape die-cutting shape is complete, and start normal operation.
[0082] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
