This patent includes: a base; a feeding mechanism for supplying tape, wherein the number of feeding mechanisms is at least two, with at least one feeding mechanism on each side of the base and symmetrically distributed; a feeding mechanism installed on the base, the feeding mechanism including a feeding drive and multiple sets of first clamping assemblies, each set of first clamping assemblies corresponding to one feeding mechanism, the feeding drive capable of driving multiple sets of first clamping assemblies to move synchronously, so that multiple sets of first clamping assemblies can simultaneously clamp and convey the tape supplied by the feeding mechanism; and a cutting mechanism installed on the base for cutting the tape. The above-described tape cutting device allows multiple sets of first clamping assemblies to be driven by the same feeding drive to simultaneously clamp and convey the tape, resulting in low cost and low energy consumption.

[0003] In the existing tape cutting process, it is necessary to manually align the long roll of tape with the blade to prevent the tape from being skewed during cutting, which would result in the tape being scrapped. Therefore, the present invention aims to provide a cutting device that can automatically feed the tape and perform tape position calibration. Summary of the Invention

[0004] To address the technical problems mentioned in the background section, the present invention provides an automated tape arrangement and cutting device.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0006] An automated tape arrangement and cutting device includes a circular conveyor and a frame. An intermittent feeding mechanism is mounted on the frame directly above the circular conveyor. The intermittent feeding mechanism includes a vertically arranged feeding pipe with a first opening and a second opening vertically spaced apart on its side wall. A rotating shaft is mounted on the frame next to the first opening. Rotating discs are sleeved at both ends of the rotating shaft. Several limiting rods extend from the outer circumference of the rotating discs. A limiting disc is also sleeved on the rotating shaft, moving synchronously with the rotating discs. Limiting grooves are formed on the edges of the limiting discs. An upper rotating rod is hinged to the frame, with a limiting block at its free end that mates with the limiting groove. A further limiting rod is hinged to the frame next to the second opening. The conveyor has a lower rotating rod, the free end of which is located inside the feed pipe. The middle part of the lower rotating rod is connected to the upper rotating rod via a linkage rod. A vertical tension spring is installed between the upper rotating rod and the frame. One end of the tension spring is connected to the frame, and the other end is connected to the middle part of the upper rotating rod. A third opening is provided on the outer side of the feed pipe between the upper and lower rotating rods. A baffle is hinged in the third opening. The baffle is connected to the frame via a gas spring. The free end of the piston rod of the gas spring is hinged to the baffle, and the bottom of the cylinder of the gas spring is hinged to the frame. The annular conveyor is equipped with several sets of positioning components, each including two spaced-apart limit claws. A cutting component is located at the end of the annular conveyor.

[0007] As a preferred embodiment, a support block is provided on the upper surface of the annular conveyor located on the side of the limiting claw. The support block is connected to the outer side of the limiting claw by a compression spring, and the limiting claw is slidably connected to the upper surface of the annular conveyor.

[0008] As a preferred embodiment, the upper end of the limiting claw is inclined outward.

[0009] As a preferred embodiment, the feeding pipe includes an upper pipe and a lower pipe that are connected to each other. The upper pipe has a cross-section shaped like a hopper, and the lower pipe has a flat box shape.

[0010] As a preferred embodiment, the cutting component includes a plurality of cutting blades spaced apart along the width direction of the annular conveyor, each cutting blade being connected via a central shaft, the free end of which is connected to a first pulley, and also includes a speed reducer, on which a second pulley is fitted, the first pulley and the second pulley being connected via a belt drive.

[0011] As a preferred embodiment, the annular conveyor includes a horizontally arranged frame, with a drive sprocket assembly hinged to one side of the feed end of the frame and a driven sprocket assembly hinged to one side of the discharge end. The drive sprocket assembly includes two main sprockets spaced apart, and the driven sprocket assembly includes two driven sprockets spaced apart. The main sprockets and driven sprockets located on the same side of the frame are connected by an annular chain drive.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. Due to the intermittent feeding mechanism, it can cooperate with the positioning components on the circular conveyor to automatically complete the positioning and arrangement of the tape before it is cut by the cutting component. The gas spring controls the dropping interval of adjacent tapes, so that the speed of the circular conveyor matches the dropping speed of the intermittent feeding mechanism, thereby improving the efficiency of tape cutting.

[0014] 2. Due to the combination of the limiting claw and the compression spring, the tape can be laterally limited by the resistance of the compression spring, and its central axis position is set perpendicular to the cutting part, which improves the cutting accuracy. It is suitable for industrial production and has strong practicality. Attached Figure Description

[0020] The technical solution of this application will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1-4The diagram shows an automated tape arrangement and cutting device, comprising a circular conveyor 1 and a frame 2. An intermittent feeding mechanism is mounted on the frame 2 directly above the circular conveyor 1. The intermittent feeding mechanism includes a vertically arranged feeding pipe 3. A first opening 4 and a second opening 5 are vertically spaced apart on the side wall of the feeding pipe 3. A rotating shaft 6 is mounted on the frame 2 on the side of the first opening 4. Rotating disks 7 are sleeved at both ends of the rotating shaft 6. Several limiting rods 8 extend from the outer circumference of the rotating disks 7. A limiting disk 9 is also sleeved on the rotating shaft 6. The limiting disks 9 move synchronously with the rotating disks 7. Limiting grooves 10 are formed on the edges of the limiting disks 9. An upper rotating rod 11 is hinged to the frame 2. A limiting block 12 that cooperates with the limiting groove 10 is provided at the free end of the upper rotating rod 11. A lower rotating rod is hinged to the frame 2 on the side of the second opening 5. 13. The free end of the lower rotating rod 13 is located inside the feed pipe 3. The middle part of the lower rotating rod 13 is connected to the upper rotating rod 11 via a linkage rod 14. A vertical tension spring 15 is provided between the upper rotating rod 11 and the frame 2. One end of the tension spring 15 is connected to the frame 2, and the other end is connected to the middle part of the upper rotating rod 11. A third opening 21 is provided on the outer side of the feed pipe 3 between the upper rotating rod 11 and the lower rotating rod 13. A baffle 22 is hinged inside the third opening 21. The baffle 22 is connected to the frame 2 via a gas spring 23. The free end of the piston rod of the gas spring 23 is hinged to the baffle 22. The bottom of the cylinder of the gas spring 23 is hinged to the frame 2. Several sets of positioning components are provided on the annular conveyor 1. The positioning components include two spaced-apart limit claws 16. A cutting component is provided at the end of the annular conveyor 1. A support block 17 is provided on the upper surface of the annular conveyor 1 located on the side of the limiting claw 16. The support block 17 is connected to the outer side of the limiting claw 16 by a compression spring 18. The limiting claw 16 is slidably connected to the upper surface of the annular conveyor 1. Specifically, the sliding connection of the limiting claw can be achieved by opening a groove. The upper end of the limiting claw 16 is inclined outward. The feed pipe 3 includes an upper pipe 301 and a lower pipe 302 that are connected to each other. The upper pipe 301 has a hopper-shaped cross-section, and the lower pipe 302 has a flat box-shaped cross-section. The cutting component includes a number of cutting blades 19 spaced apart along the width direction of the annular conveyor 1. Each cutting blade 19 is connected by a central shaft. The free end of the central shaft is connected to a first pulley. The component also includes a reducer 20. A second pulley is sleeved on the reducer 20. The first pulley and the second pulley are connected by a belt drive. The circular conveyor 1 includes a horizontally arranged frame. A drive sprocket set is hinged to one side of the feed end of the frame, and a driven sprocket set is hinged to one side of the discharge end. The drive sprocket set includes two main sprockets spaced apart, and the driven sprocket set includes two driven sprockets spaced apart. The main sprockets and driven sprockets located on the same side of the frame are connected by a circular chain drive.

[0022] During operation, the roll of tape is caught between the two limiting rods 8 of the rotating disk 7 via the feed pipe 3. In the initial state, when the previous roll of tape squeezes the rotating rod 13 to rotate clockwise, the lower rotating rod 13 pulls down the linkage rod 14, which in turn drives the upper rotating rod 11 to rotate clockwise. This causes the limiting block 12 to disengage from the limiting groove 10. Due to the gravity of the roll of tape, the limiting disk 9 rotates. The limiting disk 9 moves synchronously with the rotating disk 7, forming a continuous flow. The controllability of the gas spring 23 allows the baffle 22 to effectively delay the feeding time in the feed pipe 3. Specifically, the reciprocating extension and retraction of the piston rod of the gas spring 23 drives the baffle 22 to rotate, thereby controlling the free end of the baffle 22 to abut against the outer surface of the roll of tape located in the feed pipe 3, creating damping. Due to gravity, the roll of tape... The extrusion baffle 22 rotates slowly counterclockwise, extending the time for the roll of tape to fall, thus allowing sufficient time for cutting. Simultaneously, when the roll of tape passes the lower rotating rod 13, the positioning component on the circular conveyor 1 moves to below the feed pipe 3, and the roll of tape falls vertically between the two limiting claws 16. The distance between the two limiting claws 16 is set to be less than the diameter of the roll of tape. The weight of the roll of tape pushes the two limiting claws 16 outward, while the resetting action of the compression spring 18 limits the direction of the roll of tape, ensuring that the central axis of the roll of tape is always perpendicular to the cutting direction of the cutting component. The circular conveyor 1 drives the roll of tape to the cutting blade 19, and the relative motion between the circular conveyor 1 and the high-speed rotating cutting blade 19 completes the cutting of the roll of tape.
