Description

Technical Field

[0001] This utility model relates to the field of lighting production technology, and in particular to a punching structure for a cord lamp. Background Technology

[0002] PVC string lights, also known as PVC flexible cord lights, consist of conductors, a protective sheath covering the conductors, and a chip connected to the conductors on the protective sheath. The lamp holder is integrated onto the chip. Production typically involves prefabricating or procuring the protective sheath containing the conductors and sheath, then encapsulating the chip with the integrated lamp holder onto the protective sheath. The core process is the separation of the protective sheath at designated locations on the protective sheath.

[0003] The current process involves first cutting the rubber sheet along its length at a designated location on the cable. The cut rubber is then heated and peeled off manually or mechanically. However, the rubber between the cable conductors remains uncut, making peeling extremely difficult regardless of whether done manually or mechanically. If mechanical methods are used for punching, the mechanical heating process requires extremely high temperatures to soften the entire piece of rubber, demanding stringent temperature control. Furthermore, the high-temperature working environment poses safety hazards to workers. Additionally, the rubber sheet must be allowed to cool down after heating before processing, significantly slowing down the finishing process.

[0004] In summary, the existing rubber stripping technology has shortcomings in terms of ease of peeling, efficiency, cost, and safety, and urgently needs technological improvement to achieve the goal of making the rubber strip easier to peel off.

[0005] Therefore, it is necessary to improve existing technologies. Utility Model Content

[0030] The following embodiments illustrate the present invention, but the present invention is not limited to these embodiments. Modifications to the specific implementation of the present invention or equivalent substitutions for some technical features, without departing from the spirit of the present invention, should all be covered within the scope of the technical solution claimed by the present invention.

[0031] like Figures 1 to 7 As shown, a rubber strip punching structure for a rubber strip light is mounted on a frame and includes a fixing device 1, a cutting device 2, and a driving device 3. The fixing device 1 includes a first fixing seat 11 and a second fixing seat 12. The driving device 3 is mounted on the first fixing seat 11, and the second fixing seat 12 is disposed directly below the driving device 3. The cutting device 2 includes an upper cutting structure 21 and a lower cutting structure 22. The lower end of the driving device 3 is connected to the upper cutting structure 21, and the lower cutting structure 22 is mounted on the top of the second fixing seat 12. The driving device 3 is used to drive the upper cutting structure 21 to move up and down, so that the upper cutting structure 21 and the lower cutting structure 22 form an opening and closing motion to cut the rubber on the outer surface of the rubber strip 4.

[0032] The present invention proposes a rubber-cutting structure for a rubber lamp, which can quickly cut the rubber at a designated position on the rubber lamp 4, which facilitates the rapid removal of the rubber and not only improves production efficiency but also ensures the stability of product quality.

[0033] Specifically, the upper cutting structure 21 includes an upper left blade 211, an upper right blade 212, blades 213, and an upper blade holder 214. The lower middle end of the upper blade holder 214 has a blade groove 2141, and several blades 213 are respectively installed in the corresponding blade grooves 2141. The blades 213 are arranged parallel to the movement direction of the cable 4. The cable light consists of wires, a protective sheath covering the wires, and a chip. The wires are wrapped with rubber. The blades 213 can cut the rubber between the wires. During punching, the rubber between the wires is more easily removed because it has already been cut.

[0034] The upper left blade 211 and the upper right blade 212 are respectively installed on both sides of the upper blade holder 214, and the upper left blade 211 and the upper right blade 212 are arranged perpendicular to the movement direction of the rubber cord 4. The arrangement of the upper left blade 211 and the upper right blade 212 allows the rubber cord 4 to be cut along its length at the specified dimensions.

[0035] Furthermore, the lower cutting structure 22 includes a lower left blade 221, a lower right blade 222, and a lower blade holder 223. A limiting structure 2231 is provided on the top of the lower blade holder 223 for the passage of the rubber cable 4. When the plurality of blades 213 move downward, they can extend into the limiting structure 2231 and cut the rubber on the outer surface of the rubber cable 4. The limiting structure 2231 confines the rubber cable 4 within a specified space, preventing positional displacement during the movement of the rubber cable 4 and thus avoiding inconsistent rubber cutting quality.

[0036] The lower left blade 221 and the lower right blade 222 are respectively installed on both sides of the limiting structure 2231. The lower left blade 221 cooperates with the upper left blade 211, and the lower right blade 222 cooperates with the upper right blade 212. The lower left blade 221 and the upper left blade 211 are positioned to match each other, and the lower right blade 222 and the upper right blade 212 are positioned to match each other. The cooperation between the blades on each side realizes the cutting of the front and rear rubber of the leather line 4 along its length.

[0037] Furthermore, a third fixing seat 13 is provided on the second fixing seat 12. The third fixing seat 13 includes a fixing part 131 and a cable holder 132. The cable holder 132 is formed by bending the upper ends of the fixing part 131 on both sides. The lower cutting structure 22 is located between the two cable holders 132. The cable holder 132 serves as a guide to prevent the cable 4 from folding or bending, allowing the cable 4 to move smoothly within the limiting structure 2231.

[0038] Preferably, the third fixing seat 13 is detachably connected to the second fixing seat 12. The third fixing seat 13 is provided with an elongated hole 133, through which the height of the third fixing seat 13 on the second fixing seat 12 can be adjusted. The elongated hole 133 allows operators to easily adjust the height of the third fixing seat 13 as needed to adapt to more application scenarios.

[0039] Furthermore, each of the upper left blade 211, the upper right blade 212, the lower left blade 221, and the lower right blade 222 is provided with a connecting portion 6 and a cutting edge 5. The connecting portion 6 is located on both sides of the cutting edge 5 to protect it. The cutting edge 5 is used to cut rubber. The connecting portion 6 allows the upper left blade 211 to make limited contact with the lower left blade 221, and the upper right blade 212 to make limited contact with the lower right blade 222, while also protecting the cutting edge 5.

[0040] In addition, upper guard edges 2142 are provided on both sides of the upper blade holder 214, and the upper left blade 211 and the upper right blade 212 are respectively installed in the upper guard edges 2142;

[0041] The lower blade holder 223 has lower guard edges 2232 on both sides, and the lower left blade 221 and the lower right blade 222 are respectively installed in the lower guard edges 2232. The setting of the upper guard edge 2142 and the lower guard edge 2232 is conducive to the accurate positioning of the lower left blade 221, lower right blade 222, upper left blade 211 and upper right blade 212 during installation. Moreover, it can also effectively prevent changes in operation and impact on product quality caused by the displacement of the side blades during daily use.

[0042] Furthermore, the driving device 3 includes a cylinder 31, a linear guide rail 32, and a slider 33. The cylinder 31 is fixedly mounted on the upper end of the first fixed base 11, and the linear guide rail 32 is provided on the first fixed base 11. The slider 33 moves up and down on the linear guide rail 32 under the action of the cylinder 31. The upper cutting structure 21 is detachably mounted on the bottom end of the slider 33. The linear guide rail 32 allows the slider 33 to move up and down in a straight line, thereby ensuring the precise movement trajectory of the upper cutting structure 21.

[0043] Furthermore, the lower cutting blade structure 22 is detachably mounted on the second fixed base 12. The detachable design of the upper cutting blade structure 21 and the lower cutting blade structure 22 allows operators to easily replace the upper cutting blade structure 21 or the lower cutting blade structure 22 when the blade edge 5 becomes dull after long-term use, ensuring the working efficiency of the equipment and the quality of the product.

[0044] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
