Description

Technical Field

[0001] This utility model relates to an automatic cutting device for telephone coil hair ties. Background Technology

[0002] Telephone cord hair ties are named for their resemblance to telephone cords, with their concentric textures giving them a retro yet fashionable feel. They possess excellent elasticity, holding hair firmly and preventing slippage. Even after repeated pulling, they quickly return to their original shape without easily deforming. Currently, the manufacturing process for telephone cord hair ties involves manually removing the pre-shaped telephone cord material, cutting it into sections, and then manually assembling them into hair ties. Chinese Patent Application No. 202322243256.2 discloses a telephone cord hair tie or bracelet cutting device, comprising: a chassis base; a synchronous belt conveyor mechanism for conveying materials between upper and lower synchronous belt conveyors; a sleeve around which materials are wound; a cutting component for cutting the materials; a receiving tray located at the end of the lower synchronous belt conveyor mechanism; and a clamping component for holding the sleeve. The telephone coil hair tie or bracelet cutting device described above can cut pre-shaped hair ties or bracelets into segments of uniform length, improving production efficiency and product quality. However, it still has the following shortcomings: due to the limited length of material wound on the sleeve, it is necessary to manually replace the sleeve with material in a timely manner and feed one end of the material into the synchronous belt conveyor mechanism; furthermore, the cutting component can only complete the cutting of one segment of material at a time, and the cutting efficiency still needs to be improved.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0033] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0034] like Figures 1-4 As shown, this utility model provides an automatic cutting device for telephone coil type hair ties, comprising:

[0035] Base 1;

[0036] A pair of support plates 2 are arranged parallel to each other on the machine base, and multiple pairs of slots 201 are arranged in pairs on the pair of support plates, with the multiple pairs of slots being arranged at the same height.

[0037] Multiple sleeve rods 3 are detachably and one-to-one locked into multiple pairs of slots; rubber pads can be installed in the multiple pairs of slots to increase the friction between the multiple sleeve rods and the multiple pairs of slots and prevent the sleeve rods from rotating.

[0038] A pair of support frames 4 are respectively set on both sides of a pair of support plates, and the pair of support frames and the pair of support plates are set parallel to each other.

[0039] The crossbeam 5 is slidably mounted on a pair of support frames, and the crossbeam and the pair of support plates do not contact each other.

[0040] Multiple cutting components 6 are evenly spaced below the crossbeam and detachably mounted on the crossbeam via a telescopic rod 7. Each cutting component includes a U-shaped bracket 601; a pair of protective partitions 602, respectively mounted on the ends of two sides of the U-shaped bracket, each partition extending gradually inward toward the U-shaped bracket relative to its end; the spacing between the front edges of the pair of protective partitions is adapted to the width of the telephone coil material rope; the length of the pair of protective partitions is greater than or equal to the thickness of the telephone coil material rope 100; and the pair of partitions are detachably secured to both sides of a telephone coil material rope on the sleeve rod; a sliding sleeve 603 is disposed through the middle of the bottom of the U-shaped bracket, the axis of the sliding sleeve being parallel to the plane of the U-shaped bracket. A sliding sleeve is slidably mounted on the front end of the telescopic rod, with the blade 604 positioned between the two sides of the U-shaped bracket. The back of the blade is fixed to the front end of the telescopic rod, and the cutting edge is positioned near the ends of the two sides of the U-shaped bracket. The plane of the cutting edge is at a certain angle to the plane of the pair of protective partitions. The width of the cutting edge is greater than or equal to the width of the telephone coil-type raw material rope. A return spring 605 is mounted on the front end of the telescopic rod, with one end fixed to one end of a collar located at the bottom of the U-shaped bracket, and the other end fixed to the outer wall of the telescopic rod or the cutting blade. In the length direction of the telescopic rod, the stretchable length of the return spring is greater than the maximum distance between the cutting edge and the front end of the pair of protective partitions. At the start of the cutting operation, the telescopic rod extends, and multiple cutting pieces move downwards towards the sleeve rod until a pair of protective partitions on any cutting piece first contact the telephone coil-type raw material rope. Under the push of the telescopic rod, they are inserted into both sides of a telephone coil-type raw material rope. The telescopic rod then extends further. At this point, because the pair of protective partitions are blocked from moving forward, the front end of the telescopic rod slides in the collar, the telescopic spring is stretched, and the cutting blade is pushed out from both sides of the U-shaped bracket until the cutting blade contacts and cuts the telephone coil-type raw material rope to complete the cutting operation.

[0041] In this solution, a pair of support plates are used to hold multiple sleeve rods through multiple pairs of slots. The sleeve rods are wrapped with shaped telephone coil-type raw material ropes so that the telephone coil-type raw material ropes on the sleeve rods can be cut at equal intervals by multiple cutting parts.

[0042] Multiple cutting pieces are evenly spaced on the crossbeam. The spacing between the multiple cutting pieces can be adjusted according to production needs. Then, the crossbeam slides on a pair of support frames to the corresponding sleeve rod, and the telescopic rod is extended until the cutting blades of the multiple cutting pieces simultaneously cut the telephone coil hair tie raw material rope on the corresponding sleeve rod into equal segments. After that, the telescopic rod is retracted, and the crossbeam is slid to the next sleeve rod to continue the cutting operation.

[0043] The automatic cutting device for telephone coil hair ties provided by this utility model can simultaneously cut a whole wire of telephone coil hair tie raw material rope into multiple equal segments in one go, thereby effectively improving cutting efficiency.

[0044] like Figure 5 As shown, in a preferred embodiment, it further includes a retaining ring 701, which is sleeved on the outer part of the telescopic rod of the U-shaped bracket. When the blade is in the cutting position flush with the front end of a pair of protective spacers, the retaining ring abuts against the other end of the sliding sleeve. The retaining ring is used to limit the cutting assembly, prevent the cutting blade from overextending, protect the cutting blade and the sleeve rod, and extend its service life. The structure is simple and easy to use. In actual use, a rubber ring can be provided on the contact surface between the retaining ring and the sliding sleeve for cushioning protection to avoid impact.

[0045] In a preferred embodiment, the front ends of the pair of protective spacers are configured with arc-shaped edges, and the curvature of the arc-shaped edges matches the curvature of the outer wall of any one of the plurality of sleeve rods. In this embodiment, setting the front ends of the pair of protective spacers with arc-shaped edges allows for better adaptation to the sleeve rods and effectively protects and limits the cutting of the telephone coil hair tie material rope, ensuring that only one is cut and avoiding accidental operation.

[0046] like Figure 6 As shown, in a preferred embodiment, it further includes: a pair of limiting plates 606, which are respectively disposed on the outer side walls of a pair of protective partitions, and the pair of limiting plates are disposed at the ends near the two sides of the U-shaped bracket. The pair of limiting plates are arc-shaped plates extending along the length direction of the sleeve rod. The curvature of any limiting plate is adapted to the outer side wall of the telephone coil type raw material rope, and in the length direction of the U-shaped bracket, the distance between the middle of any limiting plate and the front edge of the pair of protective partitions is adapted to the thickness of the middle part of the telephone coil type raw material rope. A pair of limiting plates are used for auxiliary positioning. When the pair of protective spacers do not clamp a telephone coil hair tie material rope, the pair of limiting plates do not contact the telephone coil hair tie material rope, and the pair of protective spacers can slide within a small range until the pair of protective spacers clamp a telephone coil hair tie material rope, at which point the position moves forward a small distance. At the same time, the pair of limiting plates are fastened to the two telephone coil hair tie material ropes on the outside of the pair of protective spacers, thereby increasing the contact area between the pair of limiting plates and the telephone coil hair tie material rope. During the cutting operation of the cutting blade, the pair of spacers can be effectively prevented from shifting, ensuring the accuracy of the cutting.

[0047] like Figure 7As shown, a preferred embodiment further includes: a pair of slide rails 8, which are mounted on a pair of support frames, and a crossbeam slidably mounted on the pair of slide rails via a pair of sliders; a lead screw 9, which extends horizontally on the outside of any support plate via a pair of support columns, and is parallel to the pair of slide rails; and a lead screw motor 10, which is mounted on the lead screw and connected to any one of the sliders via a connecting rod 11, and synchronously drives the pair of sliders to slide. In this embodiment, the lead screw motor drives the crossbeam to slide on the pair of slide rails, allowing it to move precisely to the top of multiple sleeve rods in sequence, and sequentially cut the raw material ropes of telephone coil hair ties, quickly completing the equidistant cutting operation of multiple raw material ropes of telephone coil hair ties.

[0048] In a preferred embodiment, the tail ends of the telescopic rods of the multiple cutting parts are detachably fixed to the crossbeam by bolts; the telescopic rods are electric telescopic rods or pneumatic telescopic rods.

[0049] In a preferred embodiment, the plane of the cutting edge is set at an angle of 30° to 150° to the plane of the pair of protective partitions, such as 30°, 50°, 70°, 90°, 120°, or 150°. When the plane of the cutting edge is set at a 90° angle to the plane of the pair of protective partitions, the length of the cutting edge is the same as the width of a telephone coil hair tie material cord, so that a telephone coil hair tie material cord can be cut nearly vertically; when the plane of the cutting edge is set at other angles to the plane of the pair of protective partitions, the length of the cutting edge is greater than the width of a telephone coil hair tie material cord, so that a telephone coil hair tie material cord can be cut diagonally.

[0050] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
