Abstract
Description
Technical Field
[0001] This utility model relates to a bead-planting machine, and in particular, bead-planting equipment for the production of reflective high-gloss lettering film. Background Technology
[0002] In the production of lettering film, a beading machine is typically used to attach glass microbeads to a layer of the film to give it a reflective, high-gloss effect. Existing beading machines generally use a vibrating screen to directly sprinkle the glass microbeads onto the adhesive-coated film from above, or directly discharge the adhesive-coated film through a hopper containing glass microbeads. Regardless of the method, in practice, some glass microbeads accumulate on top of the film, requiring removal during processing. These removed microbeads often carry a small amount of adhesive, making them unusable. Furthermore, some glass microbeads fall off during the film's movement; these are often broken and cannot be reused, leading to a high consumption of glass microbeads and increased overall production costs. Therefore, existing beading machines suffer from high production costs. Utility Model Content
[0003] The purpose of this invention is to provide a bead-planting device for producing reflective high-gloss lettering film. This invention has the advantage of low production cost.
[0004] The technical solution of this utility model: a bead-planting device for producing reflective high-gloss lettering film, including a frame, bead-planting guide rollers, and multiple guide rollers. The frame is equipped with an inclined bead-planting plate. Support seats are installed on both sides of the bead-planting plate on the frame, and an adjusting shaft for fixing the bead-planting plate is rotatably installed between the two support seats. Each support seat has a mounting through hole corresponding to the position of the adjusting shaft, and each mounting through hole is threaded with a locking bolt for fixing the adjusting shaft. The adjusting shaft can drive the entire bead-planting plate to rotate, thereby adjusting the inclination angle of the bead-planting plate, which facilitates the bead-planting work of glass microspheres of different weights and improves the flexibility of use. The bead-planting work using the inclined bead-planting plate makes full use of the interaction between the weight of the glass microspheres and the inclination angle of the bead-planting plate, avoiding the accumulation of glass microspheres at the discharge end of the bead-planting plate, ensuring the bead-planting effect, and preventing excess glass microspheres from being carried away from the bead-planting plate and causing damage to the glass microspheres, avoiding unnecessary waste of glass microspheres, and reducing the overall production cost.
[0005] In the aforementioned bead-planting equipment for producing reflective high-gloss lettering film, the end of the bead-planting plate near the bead-planting guide roller is located below the end of the bead-planting plate away from the bead-planting guide roller; the tilt angle of the bead-planting plate is 4° to 5°.
[0006] In the aforementioned bead-planting equipment for producing reflective high-gloss lettering film, a slide rail is installed at the position of each support seat on the frame, and each slide rail has multiple evenly distributed locking grooves; a sliding seat is slidably installed on each slide rail, and a locking pin is slidably installed on each sliding seat. The locking pin and the locking groove cooperate to fix the position of the sliding seat on the slide rail; the support seat is set on the sliding seat; by pushing the sliding seat to move on the slide rail, the distance between the end of the bead-planting plate and the bead-planting guide roller bracket can be adjusted to suit the bead-planting work of film cloths of different thicknesses, further improving the flexibility of use; and the setting of the locking pin and the locking groove allows the position between the sliding seat and the slide rail to be fixed when no movement is required, ensuring the stability of use.
[0007] In the aforementioned bead-planting equipment for producing reflective high-gloss lettering film, a push cylinder is provided on each slide rail of the frame at a position away from the other slide rail. The end of the push cylinder is connected to the side of the sliding seat and is used to push the sliding seat to slide on the slide rail. Using a moving cylinder to push makes it convenient to use.
[0008] In the aforementioned bead-planting equipment for producing reflective high-gloss lettering film, both ends of the adjusting shaft are fitted with limit rings, the outer diameter of which is larger than the diameter of the mounting through hole; the limit rings can prevent the adjusting shaft from detaching from the support base, thus ensuring the stability of the structure.
[0009] In the aforementioned bead-planting equipment for producing reflective high-gloss lettering film, a fixed square sleeve is installed in the middle of the adjusting shaft; the bead-planting plate is welded onto the fixed square sleeve; the fixed protective sleeve is used to connect the bead-planting plate and the adjusting shaft, which increases the connection area between the adjusting shaft and the bead-planting plate and ensures the stability of the structure.
[0010] In the aforementioned bead-planting equipment for producing reflective high-gloss lettering film, a receiving hopper is provided on the frame at a position directly below the bead-planting plate; the receiving hopper can be used to collect and recycle some of the fallen glass microbeads, which facilitates cleaning.
[0011] Compared with the existing technology, this utility model improves upon the existing frame by setting two support seats, with an inclined bead-planting plate installed between the two support seats. The inclined bead-planting plate allows the glass microspheres falling on it to slowly roll towards the connection point between the bead-planting plate and the bead-planting guide roller under their own gravity. Because of the slope of the bead-planting plate, the glass microspheres do not pile up at the connection point, thus ensuring the bead-planting effect while preventing a large number of glass microspheres from being adhered to the film cloth when it passes through. As the membrane is carried away from the bead-planting plate, it eventually falls into the external environment or is damaged during subsequent collection, reducing production costs. At the same time, by rotating an adjustment shaft on the support base and placing the bead-planting plate on the adjustment shaft, and by setting a locking bolt between the adjustment shaft and the support base, the tilt angle of the bead-planting plate can be adjusted by rotating the adjustment shaft by loosening the locking bolt. Fixing the locking bolt increases the tightness of the connection between the adjustment shaft and the support base, thereby ensuring that the bead-planting plate maintains a stable angle during the bead-planting process, ensuring operational stability and increasing the flexibility of use.
[0012] Furthermore, this invention also features slide rails on the frame, each with a sliding seat slidably mounted for fixing the support base. This allows adjustment of the distance between the end of the bead-planting plate and the bead-planting guide roller bracket by pushing the sliding seat along the slide rails, making it suitable for bead-planting work on film fabrics of different thicknesses and further improving operational flexibility. The locking pins and locking grooves ensure that the position between the sliding seat and the slide rail can be fixed when no movement is required, guaranteeing operational stability. Finally, a push cylinder is installed on the frame to push the slide... The movable base frees up manpower and facilitates use. By fitting limit rings at both ends of the adjusting shaft, with the outer diameter of the limit rings larger than the diameter of the mounting through hole, the adjusting shaft is prevented from falling off the support, ensuring stability during use. A fixed square sleeve is provided in the middle of the adjusting shaft to connect the bead-planting plate; the planar structure of the outer side of the fixed square sleeve increases the connection area between the bead-planting plate and the adjusting shaft, further ensuring structural stability. A receiving hopper is provided on the frame to collect and recycle some of the fallen glass microspheres, facilitating cleaning. Therefore, this invention not only reduces production costs but also has the advantages of high flexibility, good bead-planting effect, high operational stability, and ease of use.

Detailed Implementation
[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.
[0018] Example. A bead-planting device for producing reflective high-gloss lettering film, configured as follows: Figures 1 to 3 As shown, the machine includes a frame 1, a bead-planting guide roller 2, and multiple guide rollers. The frame 1 is equipped with an inclined bead-planting plate 3. Support seats 4 are installed on the frame 1 at positions corresponding to both sides of the bead-planting plate 3. An adjustment shaft 5 for fixing the bead-planting plate 3 is rotatably installed between the two support seats 4. Each support seat 4 is provided with a mounting through hole at the position corresponding to the adjustment shaft 5. A locking bolt 7 for fixing the adjustment shaft 5 is threaded onto each mounting through hole.
[0019] The end of the bead-planting plate 3 near the bead-planting guide roller 2 is located below the end of the bead-planting plate 3 away from the bead-planting guide roller 2; the inclination angle of the bead-planting plate 3 is 4° to 5°; a slide rail 8 is installed on the frame 1 at the position corresponding to each support seat 4, and each slide rail 8 is provided with multiple evenly distributed locking grooves 9; a sliding seat 10 is slidably installed on each slide rail 8, and a locking pin 11 is slidably installed on each sliding seat 10. The locking pin 11 and the locking groove 9 cooperate with each other to fix the position of the sliding seat 10 on the slide rail 8; the support seat 4 is set on the slide rail 8. On the movable seat 10; on the frame 1, a push cylinder 15 is provided at a position away from the other slide rail 8 on each slide rail 8. The end of the push cylinder 15 is connected to the side of the slide seat 10 and is used to push the slide seat 10 to slide on the slide rail 8; both ends of the adjusting shaft 5 are fitted with limit rings 12, the outer diameter of the limit rings 12 is larger than the diameter of the mounting through hole 6; a fixed square sleeve 13 is installed in the middle of the adjusting shaft 5; the bead plate 3 is welded to the fixed square sleeve 13; a receiving hopper 14 is provided on the frame 1 at a position directly below the bead plate 3.
[0020] Working principle: In actual operation, the entire device is first placed on a horizontal surface and connected to the adhesive coating station of the lettering film. Then, the film coated with adhesive layer is passed from bottom to top between the bead guide roller 2 and the bead plate 3, and then transferred to the subsequent process by the guide roller (at this time, the side of the film coated with adhesive layer faces the bead plate 3). Next, the glass microspheres to be sprinkled evenly on the bead plate 3 (here, a sieve tray can be used, or a discharge channel of the same length as the bead plate 3 can be connected to the discharge port of the hopper storing glass microspheres). Because the bead plate 3 is set at an incline of only 4 to 5 degrees, the microspheres sprinkled on the bead plate 3 are evenly distributed. The glass microspheres will slowly move between the beading plate 3 and the beading guide roller 2 under their own gravity. When they reach the beading plate 3 and the beading guide roller 2, the bottom row of glass microspheres will adhere to the beading plate 3 and be carried away from the beading plate 3 as the engraving film moves, while the glass microspheres behind will continue to roll forward. The beading method of using an inclined beading plate can effectively avoid the accumulation of glass microspheres between the beading plate 3 and the beading guide roller 2. This ensures the beading effect and also avoids the phenomenon of the film carrying excess glass microspheres during the movement, thus avoiding unnecessary waste of glass microspheres and reducing production costs.
[0021] When the angle of the bead-planting plate 3 needs to be adjusted, simply rotate the locking bolt 7 outward to reduce the tightness of the connection between the adjusting shaft 5 and the support base 4. Then rotate the adjusting shaft 5. During the rotation of the adjusting shaft 5, the fixed square sleeve 13 will rotate, and the fixed square sleeve 13 will rotate, causing the bead-planting plate 3 to rotate along the central axis of the adjusting shaft 5. After the angle of the bead-planting plate 3 is adjusted, rotate the locking bolt 7 inward to increase the tightness of the connection between the adjusting shaft 5 and the support base 4 until the adjusting shaft 5 can no longer rotate, thus completing the angle adjustment of the bead-planting plate 3. When the distance between the bead-planting plate 3 and the bead-planting guide roller 2 needs to be adjusted, simply... Remove the locking pin 11 from the locking groove 9, allowing the sliding seat 10 to slide against the slide rail 8. Then, by pushing the cylinder 15 or manually pushing, the sliding seat 10 moves along the slide rail 8. During the movement of the sliding seat 10, the support seat 4 moves, which in turn moves the adjusting shaft 5 and the bead plate 3. This allows the distance between the bead plate 3 and the bead guide roller 2 to be adjusted. After adjusting to the appropriate position, control the pushing cylinder 15 to pause or stop applying external pressure. Then, insert the locking pin 11 into the corresponding locking groove 9 to fix the connection position between the sliding seat 10 and the slide rail 8, completing the adjustment work.
