Description

Technical Field

[0001] This utility model relates to the field of tape cutting machine technology, and in particular to an inner expansion sleeve structure for a tape cutting machine. Background Technology

[0002] A tape cutting machine is a specialized device for processing tapes. It is mainly used to cut various types of tapes according to specific requirements. It features automated operation, which improves work efficiency. The cutting length, quantity, and other parameters are adjustable to adapt to different needs. It can process various common tapes such as transparent tape, electrical tape, and masking tape, and achieves high-precision cutting, ensuring a smooth cut surface and accurate dimensions. It also has certain safety protection measures to ensure the safety of operators. It plays an important role in industrial production and related fields, helping to improve the efficiency and quality of tape processing.

[0003] Existing technologies, such as the invention patent with publication number CN110549403A, disclose an inner expansion sleeve structure for a tape cutting machine. This patent employs a drive cylinder, a guiding mechanism, a jacking mechanism, and a cutting and fixing mechanism. The drive cylinder is bolted to a support frame, and a guiding mechanism is installed on the support frames on both sides of the drive cylinder. The telescopic rod at the front end of the drive cylinder is connected to a guide shaft fixing plate. The guiding mechanism includes a guide shaft and a guide shaft sleeve, with the guide shaft slidably installed inside the guide shaft sleeve. The jacking mechanism includes a jacking shaft and a jacking shaft bearing seat. The cutting and fixing mechanism includes... The tape pipe cutting machine includes a cutting spindle and an expansion sleeve seat mounted at the front end of the cutting spindle. A movable steel ball is installed in the expansion sleeve seat below the movable expansion block. The internal expansion sleeve structure of this tape pipe cutting machine utilizes an expansion sleeve seat mounted on the cutting spindle to form a rotatable internal expansion sleeve structure. Inside the expansion sleeve seat, retractable and expandable balls are installed. The outer side of the workpiece contacts the balls, resulting in low friction on the side of relative movement, thereby improving the processing accuracy of the pipe workpiece. This solves the problem in existing technologies where, when the tape is mounted on the cutting spindle and the cutting tool rotates, the tape slides relative to the cutting spindle, reducing the cutting accuracy of the tape by the rotating tool.

[0004] When using an internal expansion sleeve structure to restrict the tape, there are certain limitations to the expansion sleeve structure used in most tape tube cutting machines on the market. Its expansion range is relatively narrow. Some manufacturers produce tapes of various specifications. When the internal diameter of the tape varies greatly, the narrow expansion range of the expansion sleeve structure makes it difficult to apply to tapes of different specifications, resulting in poor structural applicability. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing expansion sleeve structures, which have a narrow expansion range, making them unsuitable for different specifications of tape and resulting in poor structural applicability. Therefore, this invention proposes an internal expansion sleeve structure for tape cutting machines.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an inner expansion sleeve structure for a tape cutting machine, comprising an assembly frame, a base plate and an expansion sleeve assembly, wherein the base plate is mounted on the upper surface of the assembly frame, a support plate is mounted on the upper surface of the base plate, and the expansion sleeve assembly is disposed on the surface of the support plate.

[0007] The expansion sleeve assembly includes a restraint unit, which includes a servo motor. The servo motor is fixedly connected to the side surface of the support plate. A bidirectional lead screw is bolted to the drive end of the servo motor. A connecting plate is slidably connected to the surface of the bidirectional lead screw. An internal threaded ring is fixedly connected to the side surface of the connecting plate. The internal threaded ring is threadedly connected to the surface of the bidirectional lead screw. A U-shaped block is fixedly connected to the side surface of the connecting plate. A rotating hole is opened on the surface of the U-shaped block. A rotating shaft is rotatably connected to the inner wall of the rotating hole. A connecting arm is fixedly connected to the surface of the rotating shaft. A connecting frame is rotatably connected to the end of the connecting arm away from the rotating shaft. A clamping block is fixedly connected to the side surface of the connecting frame.

[0008] The expansion sleeve assembly also includes a guide unit, which includes a guide rail. The guide rail is fixedly connected to the side surface of the support plate. A sealing block is bolted to the inner wall of the guide rail. A linkage slider is slidably connected to the inner wall of the guide rail. The linkage slider is fixedly connected to the side surface of the clamping block.

[0009] Preferably, the surface of the support plate is provided with a through hole, and the bidirectional lead screw is rotatably connected to the inner wall of the through hole. Under the drive of the servo motor, the bidirectional lead screw can engage with the internal thread rings on both sides, thereby driving the connecting plate to move.

[0010] Preferably, there are two connecting plates, which are arranged symmetrically about the bidirectional lead screw. The number of internal threaded rings matches the number of connecting plates. The internal threaded rings and U-shaped blocks can be connected through the connecting plates to ensure that the internal threaded rings can drive the U-shaped blocks to move during the movement.

[0011] Preferably, there are four U-shaped blocks, which are arranged diagonally about the connecting plate. The rotation axis of one end of the connecting arm can be defined by the cooperation between the U-shaped blocks and the rotating shaft.

[0012] Preferably, the connecting arm is in contact with the surface of the U-shaped block, and the end face of the connecting arm is arc-shaped. Through the cooperation between the connecting arm and the connecting frame, the clamping block can be lifted and unfolded outward in cooperation with the connecting frame during the process of the connecting arm being pushed.

[0013] Preferably, there are two clamping blocks, which are arranged symmetrically about the bidirectional lead screw. The side of each clamping block away from the bidirectional lead screw is arc-shaped. The clamping blocks can restrict the position of the film from inside the film when it is unfolded.

[0014] Preferably, there are two guide rails, which are arranged symmetrically about the support plate. The number of linkage sliders matches the number of guide rails. Through the cooperation of the guide rails and linkage sliders, the movement direction of the clamping block can be moved.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] In this invention, by setting up an expansion sleeve assembly, the film roll is placed in the restricted area formed by the clamping blocks on both sides during processing. The servo motor is turned on, and powered by the external power distribution box, it drives the bidirectional lead screw. The bidirectional lead screw meshes with the internal threaded rings on both sides. Under the action of the bidirectional lead screw, the internal threaded rings pull the connecting plate to move towards the middle of the bidirectional lead screw. While the connecting plate is moving, it cooperates with the U-shaped block and the rotating shaft to push the connecting arm. The connecting arm unfolds outward, and during the unfolding process, it cooperates with the connecting frame to push the clamping block. While unfolding, the clamping block restricts the film roll from the inside. After the film roll is restricted, it can be cut by an external cutting mechanism. By setting up the expansion sleeve assembly, the expansion range of the expansion sleeve assembly is increased, thereby reducing the problem of the relatively narrow expansion range of the expansion sleeve assembly, which leads to poor applicability of the expansion sleeve structure, and further improving the practicality of the expansion sleeve structure.

[0026] The expansion sleeve assembly 4 also includes a guide unit 42, which includes a guide rail 421. The guide rail 421 is fixedly connected to the side surface of the support plate 3. A sealing block 422 is bolted to the inner wall of the guide rail 421. A linkage slider 423 is slidably connected to the inner wall of the guide rail 421. The linkage slider 423 is fixedly connected to the side surface of the clamping block 419.

[0027] Specifically, the support plate 3 has a through hole on its surface, and the bidirectional lead screw 412 is rotatably connected to the inner wall of the through hole. Under the drive of the servo motor 411, the bidirectional lead screw 412 can engage with the internal threaded rings 414 on both sides, thereby driving the connecting plate 413 to move.

[0028] Specifically, there are two connecting plates 413, which are arranged symmetrically about the bidirectional lead screw 412. The number of internal threaded rings 414 matches the number of connecting plates 413.

[0029] In this embodiment: the internal threaded ring 414 and the U-shaped block 415 can be connected by the connecting plate 413 to ensure that the internal threaded ring 414 can drive the U-shaped block 415 to move during the movement.
