Description

Technical Field

[0001] The utility model relates to a gluing device for processing reflective cloth, in particular to a gluing device for reflective cloth with good gluing effect. Background Art

[0002] Reflective cloth is a reflective material. The reflective cloth on the market mainly uses glass beads as the internal reflective raw material. In the process of producing reflective cloth, in order to ensure that the glass beads can be stably bonded to the reflective cloth base cloth, it is generally necessary to use a gluing device to apply a layer of glue on the bead film of the reflective cloth before laying the glass beads, which is used to bond the glass beads.

[0003] At present, the gluing equipment used by manufacturers of reflective fabrics generally uses a gluing roller partially immersed in glue, and then scrapes off the excess glue with a scraper, and finally transfers the glue on the gluing roller to the bead-planting film. However, this operation method exposes a large part of the glue to the air. As the gluing roller rotates and the heat exchange between the glue and the outside air occurs, the temperature and viscosity of the glue will change, and then part of the glue will stick to the gluing roller but not transfer to the bead-planting film, affecting the overall gluing uniformity. Therefore, the existing gluing device for reflective fabric production has the problem of poor gluing effect during use. Utility Model Content

[0022] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0023] Embodiment. A gluing device for reflective fabric with good gluing effect is composed of Figures 1 to 6 As shown, it includes a frame 1, on which a feeding device is arranged, a scraping device is arranged on one side of the feeding device, and a plurality of evenly distributed material guide rollers 2 are arranged between the scraping device and the feeding device; a gantry 3 is arranged above all the material guide rollers 2, and a glue storage barrel 4 is arranged on the gantry 3; a glue lowering port 5 is arranged on the bottom surface of the glue storage barrel 4, and a main rotating shaft 6 and an auxiliary rotating shaft 7 which are symmetrically distributed are installed on the lower glue port 5; a driving device is connected between the ends of the main rotating shaft 6 and the auxiliary rotating shaft 7, and a glue roller sleeve 8 is sleeved on the main rotating shaft 6 and the auxiliary rotating shaft 7; an annular cavity 9 is arranged in the middle of each glue roller sleeve 8, and an electric heating element is arranged in the annular cavity 9.

[0024] A heat insulating member 10 is bonded to the inner bottom surface of the annular cavity 9; the scraping device includes a scraping frame 11, on which two symmetrically distributed ball screws 12 are arranged; a servo motor 13 is installed at the end of each ball screw 12, and a moving seat is slidably installed on each ball screw 12; a support rod 14 is arranged between the two moving seats, and a scraping member 15 is arranged on the bottom surface of the support rod 14; both ends of the scraping member 15 are installed with stoppers 16, and a suction pipe 17 is installed on the side of each stopper 16 facing the scraping member 15; a suction pump is connected between the ends of the two suction pipes 17, and the two suction pipes 17 are connected to the glue storage barrel 4; the feeding device includes a feeding frame 18, on which a servo motor 13 is installed. There is a feeding roller shaft 19; a guide roller 20 is arranged on one side of the feeding roller shaft 19, and a plurality of tensioning rollers 21 are arranged between the guide roller 20 and the feeding roller shaft 19; retaining rings 22 are installed on both ends of the feeding roller shaft 19 and the guide roller 20; an antistatic layer 23 is coated on the surface of the guide roller 20; a dust removal roller 24 is arranged between the guide roller 20 and the tensioning roller 21; the driving device includes a driving motor 25 installed on the main shaft 6, and a driving gear 26 located between the driving motor 25 and the glue roller sleeve 8 is arranged on one side of the driving motor 25; a driven gear 27 meshingly connected with the driving gear 26 is arranged on the secondary shaft 7; a limiting member 28 is sleeved between the two ends of all the guide rollers 2.

[0025] Working principle: When performing the gluing work, first connect the entire device to the external safe mains power, then place the reflective fabric bead film that needs to be glued on the feeding roller 19, and add a certain amount of glue to the glue storage barrel 4; then, according to the thickness of the glue to be applied, control the servo motor 13 to start, and after the servo motor 13 is started, it will drive the ball screw 12 to rotate, and after the ball screw 12 rotates, it will drive its own nut seat to move downward, because the support rod 14 is slidably connected to the ball screw 12 through the nut seat, so that the support rod 14 will be driven to move synchronously during the movement of the nut seat, so that the scraping member 15 set on the joint venture car rod 14 moves together, and when the distance between the scraping member 15 and the top surface of the guide roller 2 reaches the thickness of the glue that needs to be controlled, control the servo motor 13 to stop, so that the scraping member 15 stays at the current position.

[0026] Then, the motor connected to the feeding roller 19 is controlled to start so that the feeding roller 19 can rotate. During the rotation of the feeding roller 19, the end of the bead-planting film will be transported to pass through the tensioning roller 21, the dust removal roller 24 and the guide roller 20 in sequence. The tension of the bead-planting film can be adjusted by using multiple tensioning rollers. After the bead-planting film passes through all the tensioning rollers, it will first pass through the dust removal roller 24. The dust removal roller 24 can be used to remove dust from the surface of the bead-planting film that needs to be glued, and finally move to the guide roller 2 under the action of the guide roller 20; and the bead-planting film will slowly move to the bottom of the glue storage barrel 4 as the feeding roller 19 continues to transport and the guide roller 20 rotates and transports.

[0027] After the bead-planting film is conveyed to the guide roller 2, the control driving motor 25 and the electric heating element are powered on and started. After the driving motor 25 is started, it will drive the main shaft 6 to rotate. When the main shaft 6 rotates, it will drive the driving gear 26 to rotate. Because the driving gear 26 is meshed and connected with the driven gear 27, the driving gear 26 will drive the driven gear 27 to rotate when it rotates. After the driven gear 27 rotates, it will drive the secondary shaft 7 to rotate; when the main shaft 6 and the secondary shaft 7 are behind, the glue roller 8 will be driven to rotate, so that the glue in the glue storage barrel 4 will be transferred to the bead-planting film passing directly under the glue storage barrel 4 and in contact with the bottom surface of the glue roller 8 along with the glue roller 8; at the same time, because the rotation of the glue roller 8 will drive the glue in the glue storage barrel 4 to flow to a certain extent, and the electric heating element in the glue roller 8 will heat the surrounding glue after being energized, thereby avoiding the internal glue from solidifying, which is convenient for use.

[0028] As the guide roller 2 drives the bead-planting film to continue to move, the bead-planting film that completes the first step of gluing will move to the bottom of the scraper frame 11. When the bead-planting film passes through the scraper frame 11, the scraper 15 on the scraper frame 11 can scrape and spread the glue on the bead-planting film, so that the thickness of the glue on the bead-planting film remains consistent, and the entire gluing work is completed. At the same time, some excess glue will be blocked between the scraper 15 and the blocking member 16. When there is a certain amount of glue, the excess glue can be sucked into the glue storage barrel 4 for reuse through the suction tube 17 and the suction pump connected to the suction tube 17, thereby improving the utilization rate of the glue and reducing the production cost.
