Description

Technical Field

[0001] This utility model relates to the field of glue application equipment technology, and in particular to a glue application device for a hot melt laminating machine. Background Technology

[0002] As is well known, the glue storage stage in the glue application unit is crucial in the workflow of a hot melt laminating machine. Hot melt adhesive is a complex mixture, and its components are prone to sedimentation during storage. However, current hot melt laminating machine glue application units have significant deficiencies in glue storage.

[0003] Current adhesive application processes typically use simple containers to store the adhesive, lacking effective measures to prevent sedimentation. When hot melt adhesive is stored statically, components of different densities begin to separate due to gravity. For example, some hot melt adhesive formulations contain particulate fillers and additives; these heavier components gradually settle to the bottom of the storage container. This results in uneven adhesive composition, causing inconsistencies in the adhesive layer's adhesion and thickness when applied to materials. During hot melt lamination, this severely affects the bonding effect between materials, potentially leading to delamination and peeling during use, reducing the quality and reliability of the applied products and failing to meet current production requirements.

[0004] Therefore, this utility model proposes a glue applicator for a hot melt laminating machine to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a glue applicator for a hot melt laminating machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A glue applicator for a hot melt laminating machine includes a hot melt laminating machine, a coating drive roller disposed inside the hot melt laminating machine, and a glue storage tank disposed on the right side of the hot melt laminating machine. A glue applicator pump is disposed on the front side of the glue storage tank. The output end of the glue applicator pump is connected to a glue applicator spraying hood for spraying glue onto the material through a glue applicator pipe. The glue applicator spraying hood is located below the coating drive roller. The input end of the glue applicator pump is connected to the glue storage tank through a suction pipe.

[0008] The glue storage box is fixedly installed with a partition and a lifting plate above the partition. A first motor is fixedly installed on the top of the lifting plate. The output shaft of the first motor rotates through to the bottom of the lifting plate and is fixedly connected to a movable shaft. The bottom end of the movable shaft moves through to the bottom of the partition. Multiple stirring paddles for stirring the hot melt glue are fixedly installed on the movable shaft located below the partition.

[0009] Two vertical screws are fixedly connected between the partition and the inner top wall of the glue storage box. A threaded tube is threadedly connected to the vertical screw, and the bottom end of the threaded tube is rotatably mounted on the lifting plate through the first bearing. A second gear is fixedly sleeved on the top end of the threaded tube, and a first gear meshes with the outside of the second gear. A mounting frame is fixedly installed on the lifting plate below the first gear, and a second motor is fixedly installed on the mounting frame. The first gear is fixedly sleeved on the output end of the second motor.

[0010] Furthermore, a feeding port is provided on the upper right side of the glue storage box, and a sealing cap is provided on the feeding port.

[0011] Furthermore, guide sliders are fixedly installed at both ends of the lifting plate, and guide rails are fixedly installed on both inner walls of the glue storage box, with the guide sliders slidingly mounted on the guide rails in the vertical direction.

[0012] Furthermore, a sliding sleeve is fixedly fitted onto the partition plate, and the movable shaft slides through the sliding sleeve in a sealed manner. The movable shaft's movement trajectory within the sliding sleeve is a combination of lifting and rotating motion.

[0013] Furthermore, a second bearing is fixedly installed on the lifting plate, and the output end of the first motor is rotatably mounted on the second bearing.

[0014] Furthermore, a controller is also provided on the top side of the hot melt laminating machine, which is electrically connected to the glue pump, the first motor, and the second motor.

[0015] The beneficial effects achieved by this utility model using the above structure are as follows:

[0016] This invention not only facilitates the application of adhesive to composite materials, but also, during application, the hot melt adhesive in the adhesive storage tank can be rotated and agitated by the cooperation of the first motor, the movable shaft, and the agitator to prevent sedimentation. At the same time, the agitator can be moved up and down by the cooperation of the second motor, the first gear, the second gear, the threaded tube, the first bearing, the lifting plate, and the vertical screw to further vibrate the adhesive, resulting in a better anti-sedimentation effect.

[0017] Furthermore, the rotation and agitation of the stirring paddle, along with its lifting and vibrating motion, can work together simultaneously, resulting in a better anti-settling effect on the adhesive during the application process. This avoids the situation where existing technologies lack effective anti-settling measures, leading to the accumulation of effective adhesive components at the bottom. This ensures the uniformity of the adhesive composition during application, thereby guaranteeing the adhesive's bonding effect on the material. It also prevents the composite material from delaminating or delaminating during use due to adhesive sedimentation, ensuring product quality and greatly meeting people's needs.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-3 A glue applicator for a hot melt laminating machine includes a hot melt laminating machine 1, a coating drive roller 101 disposed inside the hot melt laminating machine 1, and a glue storage tank 2 disposed on the right side of the hot melt laminating machine 1. A glue applicator pump 3 is disposed on the front side of the glue storage tank 2. The output end of the glue applicator pump 3 is connected to a glue applicator spraying cover 303 for spraying glue onto the material through a glue applicator pipe 302. The glue applicator spraying cover 303 is located below the coating drive roller 101. The input end of the glue applicator pump 3 is connected to the glue storage tank 2 through a suction pipe 301.

[0024] A partition 202 and a lifting plate 203 located above the partition 202 are fixedly installed inside the glue storage tank 2. A first motor 204 is fixedly installed on the top of the lifting plate 203. The output shaft of the first motor 204 rotates through to the bottom of the lifting plate 203 and is fixedly connected to a movable shaft 205. The bottom end of the movable shaft 205 moves through to the bottom of the partition 202. Multiple agitators 206 for stirring the hot melt glue are fixedly installed on the movable shaft 205 located below the partition 202. The partition 202 and the glue storage tank 2 are connected. Two vertical screws 10 are fixedly connected between the top inner walls of the storage tank 2. A threaded tube 8 is threadedly connected to the vertical screws 10, and the bottom end of the threaded tube 8 is rotatably mounted on the lifting plate 203 through the first bearing 9. A second gear 7 is fixedly sleeved on the top end of the threaded tube 8, and a first gear 6 meshes with the outside of the second gear 7. A mounting bracket 4 is fixedly installed on the lifting plate 203 below the first gear 6. A second motor 5 is fixedly installed on the mounting bracket 4, and the first gear 6 is fixedly sleeved on the output end of the second motor 5.

[0025] In this embodiment, a feeding port 201 is provided on the upper right side of the glue storage box 2, and a sealing cover is provided on the feeding port 201; guide sliders 11 are fixedly provided at both ends of the lifting plate 203, and guide rails 12 are fixedly provided on both inner walls of the glue storage box 2, and the guide sliders 11 are slidably installed on the guide rails 12 in the vertical direction.

[0026] In this embodiment, a sliding sleeve 208 is fixedly sleeved on the partition 202, and the movable shaft 205 slides through the sliding sleeve 208 in a sealed manner. The movement trajectory of the movable shaft 205 based on the sliding sleeve 208 is a combination of lifting and rotating motion.

[0027] The lifting plate 203 is also fixedly installed with a second bearing 207, and the output end of the first motor 204 is rotatably installed on the second bearing 207; the top side of the hot melt laminating machine 1 is also equipped with a controller 13, which is electrically connected to the glue pump 3, the first motor 204 and the second motor 5 respectively.

[0028] like Figure 1-3The glue applicator of the hot melt laminating machine shown is used in the following way: when the material to be laminated passes through the coating transmission roller 101, the glue pump 3 works and draws glue from the glue storage tank 2 through the suction pipe 301. At the same time, it is transmitted to the glue spraying hood 303 through the glue application pipe 302. Finally, the glue is sprayed onto the composite material on the coating transmission roller 101 through the glue spraying hood 303. Furthermore, during glue application, to prevent the hot melt glue in the glue storage tank 2 from settling, the first motor 204 drives the movable shaft 205 and the agitator 206 to rotate in both directions. This rotates and agitates the hot melt glue in the glue storage tank 2, preventing settling. Simultaneously, the second motor 5 drives the first gear 6 to rotate in either direction. When the first gear 6 rotates, it meshes with the second gear 7, driving the threaded tube 8 to rotate on the first bearing 9. When the threaded tube 8 rotates, the lifting plate 203 can move upward or downward along the vertical screw 10 via the threaded tube 8 on the first bearing 9. When the lifting plate 203 moves, it also drives the first motor 204, the movable shaft 205, and the agitator. The lifting and lowering motion of the agitator 206 further vibrates the adhesive, and the rotational agitation and lifting vibration of the agitator 206 can be coordinated simultaneously. This improves the anti-sedimentation effect of the adhesive during the application process, avoiding the situation where the effective components of the adhesive tend to settle at the bottom due to the lack of effective anti-sedimentation measures in existing technologies. This ensures the uniformity of the adhesive composition during the application process, thereby ensuring the adhesive's bonding effect on the material. It also prevents the composite material from delamination or delamination due to adhesive sedimentation during use, ensuring product quality and greatly meeting people's needs.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
