Description

Technical Field

[0001] The utility model relates to the technical field of tape cutting, in particular to a tape cutting mechanism. Background Art

[0002] Most traditional tape cutting devices rely on manual operation or simple mechanical structures to complete tape cutting. This method has limitations in both efficiency and accuracy. Specifically, the operator often needs to estimate the required tape length based on experience or visual inspection and achieve cutting by manually pressing or pulling the handle. However, this operation method not only consumes time and effort but also easily leads to inconsistent cutting lengths and errors. Especially in large-scale and high-speed production environments, the accumulation of such errors will seriously affect production efficiency and product quality.

[0003] More seriously, due to the difficulty in precisely controlling the cutting length, there are often situations where the tape is too long. This not only causes waste of tape and increases production costs but also may cause inconvenience to subsequent packaging or pasting work. For example, during the packaging process, the too-long tape may not fit neatly on the packaging object, resulting in poor packaging effects; during the pasting process, the too-long tape requires additional cutting steps, reducing work efficiency.

For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0028] The following Figures 1 to 2 describes a tape cutting mechanism according to an embodiment of the present utility model.

[0029] A tape cutting mechanism includes a tape unwinding roller 421, a tape unwinding clamping assembly 422, a tape unwinding conveying assembly 423, a tape cutting assembly 424, and a tape clip.

[0030] The end of the tape is wound around the tape unwinding roller 421, the head of the tape is located at the tape unwinding clamping assembly 422, the mounting end of the tape unwinding conveying assembly 423 is mounted on the frame 1, and the conveying end of the tape unwinding conveying assembly 423 is respectively connected to the tape unwinding clamping assembly 422 and the tape cutting assembly 424.

[0031] The tape unwinding roller 421 is used for unwinding the tape, the tape unwinding clamping assembly 422 is used for clamping the end of the tape, the tape unwinding conveying assembly 423 is used for pulling the end of the tape, the tape cutting assembly 424 is used for cutting the tape, and the tape clip is used for clamping the cut tape segment.

[0032] The tape cutting mechanism 42 realizes the full-automatic processing from tape unwinding to cutting, and can complete the accurate positioning and cutting of the tape without manual intervention. This not only reduces the errors and uncertainties brought by manual operations, but also greatly improves the production efficiency, enabling the production line to operate continuously and stably.

[0033] Among them, the precise cooperation of the tape cutting assembly 424, the tape unwinding and clamping assembly 422, and the tape unwinding and conveying assembly 423 ensures that the length of the tape cut each time meets the preset requirements, and the cutting edge is neat and free of burrs. This high-precision cutting effect not only improves the appearance quality of the product but also enhances the firmness and reliability of the tape adhesion. At the same time, due to the consistency of the automated cutting, each section of the tape has the same performance, which is conducive to ensuring the overall quality of the product.

[0034] The tape unwinding and conveying assembly 423 includes a tape unwinding and conveying power member 4231, a tape unwinding and conveying slide rail 4232, and a tape unwinding and conveying slider 4233. The installation section of the tape unwinding and conveying power member 4231 is fixedly installed on the frame 1. The driving end of the tape unwinding and conveying power member 4231 is fixedly connected to the tape unwinding and conveying slider 4233. The tape unwinding and conveying slide rail 4232 is fixedly installed on the frame 1. The tape unwinding and conveying slide rail 4232 is slidably connected to the tape unwinding and conveying slider 4233. The tape unwinding and clamping assembly 422 is installed on the top of the tape unwinding and conveying slider 4233.

[0035] One end of the tape unwinding and conveying slider 4233 away from the tape unwinding roller 421 is installed with the tape cutting assembly 424.

[0036] It should be noted that the tape unwinding and conveying power member 4231 is preferably a cylinder. When the tape unwinding and conveying power member 4231 is started, the tape unwinding and conveying power member 4231 drives the tape unwinding and conveying slider 4233 to move on the tape unwinding and conveying slide rail 4232, thereby driving the tape unwinding and clamping assembly 422 to pull the tape.

[0037] The setting of the tape unwinding and conveying power member 4231 can accurately control the moving distance of the tape unwinding and conveying slider 4233 to limit the cutting length of the tape and improve the accuracy of the tape cutting device in this solution.

[0038] The tape unwinding and clamping assembly 422 includes a first tape unwinding and clamping plate 4221, a second tape unwinding and clamping plate 4222, and a tape clamping power member. The first tape unwinding and clamping plate 4221 is installed on the top of the tape unwinding and conveying slider 4233. The tape clamping power member is installed on the bottom of the tape unwinding and conveying slider 4233. The driving end of the tape clamping power member is fixedly installed with the second tape unwinding and clamping plate 4222. The second tape unwinding and clamping plate 4222 is located below the first tape unwinding and clamping plate 4221.

[0039] An activity space for the tape is formed between the first tape unwinding clamping plate 4221 and the second tape unwinding clamping plate 4222, and the tape passes through the tape unwinding clamping assembly 422 through the activity space.

[0040] It should be noted that the tape unwinding clamping power component is preferably a cylinder. When the tape unwinding clamping power component is started, the second tape unwinding clamping plate 4222 is driven by the tape unwinding clamping power component to rise, so that the first tape unwinding clamping plate 4221 and the second tape unwinding clamping plate 4222 clamp the tape together.

[0041] At this time, the tape unwinding conveying assembly 423 is started, so that the first tape unwinding clamping plate 4221 and the second tape unwinding clamping plate 4222 can pull the end of the tape outward, and the tape clamp is started so that the tape clamp can clamp the end of the tape.

[0042] Then, the tape unwinding clamping power component is continuously started, and the second tape unwinding clamping plate 4222 is driven by the tape unwinding clamping power component to descend, so that an activity space for the tape is formed between the first tape unwinding clamping plate 4221 and the second tape unwinding clamping plate 4222. The tape unwinding conveying assembly 423 is started, so that the first tape unwinding clamping plate 4221 and the second tape unwinding clamping plate 4222 return to their original positions, and the end of the tape is exposed to the outside.

[0043] The tape cutting assembly 424 is started, and the cutting blade of the tape cutting assembly 424 cuts the tape, thereby cutting the tape into tape segments of a specific length.

[0044] Among them, the tape is always located in the activity space between the first tape unwinding clamping plate 4221 and the second tape unwinding clamping plate 4222, which can effectively prevent the tape from slipping or shifting during the unwinding process. Moreover, in this solution, the activity range of the tape unwinding clamping assembly 422 can be limited to cut the tape into a specific length, thereby improving the accuracy of the cut tape length.

[0045] The tape cutting assembly 424 includes a tape cutting blade 4241 and a tape cutting power component 4242. The installation end of the tape cutting power component 4242 is located at one end of the tape unwinding conveying slider 4233 away from the tape unwinding roller 421. The driving end of the tape cutting power component 4242 is fixedly connected to the tape cutting blade 4241. The tape cutting blade 4241 is located at one end of the tape unwinding clamping assembly 422 away from the tape unwinding roller 421. The tape cutting power component 4242 is used to drive the tape cutting blade 4241 to move up and down, and the tape cutting blade 4241 is used to cut the tape.

[0046] Activate the tape cutting power component 4242, causing the tape cutting blade 4241 to move up and down at one end of the tape unwinding and clamping assembly 422 away from the tape unwinding roller 421, thereby performing automated cutting, effectively avoiding the risk of cuts that may be caused by improper operation during manual cutting. The tape cutting blade 4241 is securely fixed to the cutting power component and is remotely operated through a control system. The operator does not need to directly contact the sharp blade, thus greatly enhancing the safety during the operation process.

[0047] A tape pressing elastic sheet is provided at the front end of the tape clip, and the bottom end of the tape pressing elastic sheet horizontally abuts against the tape.

[0048] Utilizing its elastic characteristics, the tape pressing elastic sheet can gently and firmly press against the tape when the tape is placed on the surface of the magnetic core, ensuring a tight fit between the tape and the magnetic core. This not only reduces the generation of bubbles and voids but also improves the adhesion between the tape and the magnetic core, enabling the tape to adhere more effectively to the magnetic core.

[0049] The tape cutting mechanism 42 further includes a tape unwinding tensioning roller 426, and the tape unwinding tensioning roller 426 is located between the tape unwinding roller 421 and the tape unwinding and clamping assembly 422;

[0050] A tape unwinding slide rail 427 is vertically installed on the frame 1. The tape unwinding slide rail 427 is slidably connected with a tape unwinding slide block 428. The tape unwinding slide block 428 is rotatably connected to the end of the tape unwinding tensioning roller 426, and the tape unwinding tensioning roller 426 adjusts the tension of the tape in the vertical direction.

[0051] The mutual cooperation of the tape unwinding slide rail 427 and the tape unwinding slide block 428 enables the tape unwinding tensioning roller 426 to move vertically on the frame 1, flexibly adjusting the tension of the tape during the unwinding process. Among them, an appropriate tension helps to reduce the slack or excessive tightness of the tape during the unwinding process, ensuring the smooth and continuous transmission of the tape.

[0052] There are two sets of the tape cutting mechanisms 42, and the two sets of the tape cutting mechanisms 42 are arranged side by side.

[0053] The two sets of tape cutting mechanisms 42 running side by side mean that the two ends of the magnetic core can be coated with tape simultaneously, greatly shortening the tape coating cycle for a single magnetic core. Moreover, the two sets of tape cutting mechanisms 42 acting simultaneously can form a firm tape coating layer at both ends of the insulating paper, significantly reducing the risk of edge warping and enhancing the overall insulation performance and stability of the magnetic core.

[0054] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
