Description

Technical Field

[0001] This utility model belongs to the field of woven label processing technology, specifically a device for smoothing the edges of woven labels. Background Technology

[0002] In the slitting process of woven label production, edge quality is a key indicator that determines the product grade and market competitiveness. Especially for mid-to-high-end products in the fields of clothing and home textiles, the requirements for the smoothness and absence of loose threads on the label edges are extremely stringent. Woven label fabrics are mostly blends of chemical fibers (polyester, nylon, etc.) and cotton. When cut by a slitting knife, the fibers are prone to incomplete breakage and loose ends, resulting in rough edges.

[0003] Existing edge treatment solutions are mostly post-processing methods (such as ultrasonic edge melting and hot pressing edge sealing), which require a separate process after slitting, resulting in a 30% decrease in single-roll processing efficiency and the formation of rough edges, as well as uneven edge melting effects. Although high-temperature cutting can cut and seal simultaneously, the equipment cost is 5-8 times that of traditional slitting machines, and high temperatures can easily cause discoloration of woven label patterns, limiting adaptability. Therefore, we propose a woven label trademark edge smoothing treatment device. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 A woven label edge smoothing device includes a slitting machine 1. A mounting plate 11 is slidably mounted on the top of the slitting machine 1's blade holder. A concave frame 12 is fixedly mounted on the bottom right side of the mounting plate 11. A light box 19 is slidably mounted inside the concave frame 12. An infrared heating tube 2 is fixedly mounted inside the light box 19. A focusing cover 18 is fixedly mounted on the bottom of the light box 19. An electric telescopic rod 13 is fixedly mounted on the top of the light box 19. An infrared temperature probe 17 is fixedly mounted on the bottom left side of the concave frame 12. A PLC temperature controller 15 is electrically connected to the outside of the infrared temperature probe 17, the infrared heating tube 2, and the electric telescopic rod 13. The focusing cover 18 and the infrared temperature probe 17 are aligned with the slitting blade inside the slitting machine 1's blade holder. Uncut woven label fabric is introduced into the slitting machine 1 and cut by the slitting blade of the slitting machine 1. The device is then secured by locking bolts. 22 generates high-temperature infrared radiation, which is focused onto the area to be cut on the woven label fabric by the focusing cover 18, thus heating the area. When the fabric moves to the left and is below the infrared temperature probe 17, the infrared temperature probe 17 detects its temperature. When the temperature is too high, the heating temperature of the infrared heating tube 2 is controlled by the PLC temperature controller 15. The PLC temperature controller 15 can also control the electric telescopic rod 13 to work, which drives the light box 19 to move up and down, thereby changing the distance between the focusing cover 18 and the fabric, thus further changing the heating temperature of the fabric. Then the slitting knife of the slitting machine 1 cuts the fabric, thus achieving the effect of "cutting and sealing the edge", effectively solving the pain points of low efficiency and unstable quality in the traditional process of rough edge treatment.

[0020] The top of the slitting machine 1 has two sets of threaded holes evenly spaced. The top left side of the mounting plate 11 has two sets of through holes evenly spaced. Fixing bolts 16 are rotatably installed in the through holes and screwed into the threaded holes. The slitting machine 1 has threaded holes corresponding to the fixing bolts 16 on its blade holder, allowing the mounting plate 11 to be fixed to the blade holder using the fixing bolts 16. This significantly reduces the difficulty and cost of modifying the traditional slitting machine 1. The PLC temperature controller 15 and the electric telescopic rod 13 are evenly fixed on the top of the mounting plate 11. The telescopic end of the electric telescopic rod 13 passes through the bottom of the mounting plate 11 and the concave frame 12 and connects to the light box 19. The tops of the mounting plate 11 and the concave frame 12 are evenly spaced... Two sets of guide holes are evenly provided throughout the light box 19. Two sets of guide rods 14 are evenly fixedly provided on the top of the light box 19. The guide rods 14 are slidably disposed in the guide holes. Two sets of internal threaded sleeves 21 are evenly fixedly provided on the top of the mounting plate 11. Locking bolts 22 are screwed into the internal threaded sleeves 21. Anti-slip pads 23 are fixedly provided on the outside of the locking bolts 22. The anti-slip pads 23 are tightly fitted with the outer side wall of the guide rods 14. The guide rods 14 assist the light box 19 to move up and down stably. After the height of the light box 19 is adjusted, the locking bolts 22 can be tightened to make the anti-slip pads 23 tightly fitted with the guide rods 14, thereby fixing the height of the guide rods 14 and improving the stability of the light box 19 at the bottom of the guide rods 14.

[0021] Working principle: Threaded holes corresponding to fixing bolts 16 are made on the blade holder of the slitting machine 1. The mounting plate 11 can then be fixed to the blade holder of the slitting machine 1 using the fixing bolts 16. This significantly reduces the difficulty and cost of modifying the traditional slitting machine 1. When the unchopped woven label fabric is introduced into the slitting machine 1 and slitted by the slitting blades of the slitting machine 1, high-temperature infrared radiation is generated by the locking bolts 22. The high-temperature infrared radiation is focused onto the area to be slit on the woven label fabric by the focusing cover 18, thus heating this area. When the fabric moves to the left and is below the infrared temperature probe 17, the infrared temperature probe 17 detects its temperature. When the temperature is too high, the heating temperature of the infrared heating tube 2 is controlled by the PLC temperature controller 15. The electric telescopic rod 13 can be controlled by the PLC temperature controller 15 to move the light box 19 up and down, thereby changing the distance between the condenser 18 and the fabric, which in turn changes the heating temperature of the fabric. Then, the slitting knife of the slitting machine 1 cuts the fabric, thus achieving the effect of "cutting and sealing the edge". This effectively solves the pain points of low efficiency and unstable quality in the traditional process of rough edge treatment. The guide rod 14 assists the light box 19 to move up and down stably. After the height of the light box 19 is adjusted, the locking bolt 22 can be tightened to make the anti-slip pad 23 fit tightly with the guide rod 14, thereby fixing the height of the guide rod 14 and improving the stability of the light box 19 at the bottom of the guide rod 14.

[0022] It is worth noting that the PLC temperature controller 15 can establish communication with the drive module (such as a relay or servo controller) of the electric telescopic rod 13 through output control signals (such as analog signals or switch signals). For example, when the PLC temperature controller 15 detects a deviation in the preheating temperature due to changes in the thickness of the woven label through the infrared temperature probe 17, it can trigger the electric telescopic rod 13 to adjust the height of the light box 19. By changing the distance between the infrared heating tube 2 and the fabric, the actual preheating temperature is indirectly adjusted, forming a closed-loop control of "temperature feedback - position adjustment".
