Description

Technical Field

[0001] This utility model relates to the field of gluing machines, specifically a gluing machine with a low-energy-consumption hot melt adhesive rapid preheating structure. Background Technology

[0002] A laminating machine (also known as a hot melt adhesive roller) heats solid hot melt adhesive into a liquid state, and then applies it evenly to the surface of substrates such as paper and plastic under program control to achieve bonding or protection. However, existing laminating machines have limited functionality and are not convenient for synchronously adjusting the distance between the two drive rollers and the distance between the two extrusion rollers, making them unsuitable for materials of different thicknesses.

[0003] To address the aforementioned issues, a glue applicator with a low-energy-consumption hot melt adhesive rapid preheating structure is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a glue applicator with a low-energy-consumption hot melt adhesive rapid preheating structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a glue applicator with a low-energy hot melt adhesive rapid preheating structure, comprising a lower glue base, two mounting seats fixedly arranged on both sides of the lower glue base, a transmission seat fixedly arranged on the top between the four mounting seats, a lead screw rotatably arranged on the bottom inner side of each of the four mounting seats, a transmission wheel fixedly connected to the top of each of the four lead screws extending into the interior of the transmission seat, a belt driving between the four transmission wheels, a sleeve threaded on the middle of the surface of each of the four lead screws, a moving block fixedly arranged on one side of each of the four sleeves, an upper glue base fixedly arranged between the four moving blocks, a mounting groove opened in the middle of the bottom end of the upper glue base and the middle of the top end of the lower glue base, an mounting plate engaging inside each of the two mounting grooves, and several heating tubes fixedly installed on the opposite side of each of the two mounting plates.

[0006] The motor drives the drive gear to rotate. Since the drive gear meshes with the driven gear, it drives one of the lead screws to rotate. Since the four drive wheels are connected by belts, the four drive wheels rotate synchronously, which in turn drives the four lead screws to rotate synchronously, which in turn drives the four sleeves to move up and down synchronously, which in turn drives the upper rubber seat to move up and down. This allows for synchronous adjustment of the distance between the two drive rollers and the distance between the two extrusion rollers, making it suitable for materials of different thicknesses.

[0007] Preferably, a driven gear is fixedly provided at the bottom of the surface of one of the lead screws, and a motor is fixedly installed at the bottom of one side of the mounting base. The output end of the motor extends into the interior of one of the mounting bases and is fixedly connected to a driving gear. The driving gear meshes with the driven gear, and the motor drives the driving gear to rotate. Since the driving gear meshes with the driven gear, it drives one of the lead screws to rotate. Since a belt is provided between the four transmission wheels, the four transmission wheels rotate synchronously, which in turn drives the four lead screws to rotate synchronously.

[0008] Preferably, each of the four mounting seats has a moving groove in the middle of its inner side, and the four moving grooves are slidably connected to the four moving blocks respectively. The setting of the four moving grooves facilitates the stable movement of the four moving blocks.

[0009] Preferably, each of the four mounting seats and the transmission seat is provided with a rotating hole, and the eight rotating holes are respectively rotatably connected to the four lead screws. The setting of the four rotating holes facilitates the stable rotation of the four lead screws.

[0010] Preferably, a drive roller is provided on one side of the bottom end of the upper glue seat and one side of the top end of the lower glue seat, and a squeeze roller is provided on the side of the bottom end of the upper glue seat away from the drive roller and the side of the top end of the lower glue seat away from the drive roller. The arrangement of the two drive rollers facilitates the conveying of materials.

[0011] Preferably, the two mounting slots are provided with connecting slots at the connection points with the two mounting plates, and each of the four connecting slots is provided with a connecting post. The four connecting posts are fixedly connected to the two mounting plates, and the preheating structure is initially limited by the limiting engagement of the four connecting posts with the four connecting slots.

[0012] Preferably, each of the four connecting pins has an installation groove on one side, and each of the four installation grooves has a limiting spring fixedly installed inside. Each of the four connecting pin grooves has a limiting groove on one side of its inner wall, and each of the four limiting springs engages with the four limiting grooves respectively. The engagement of the four limiting springs with the four limiting grooves facilitates further limiting of the preheating structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The motor drives the drive gear to rotate. Since the drive gear meshes with the driven gear, it drives one of the lead screws to rotate. Since the four transmission wheels are connected by belts, the four transmission wheels rotate synchronously, which in turn drives the four lead screws to rotate synchronously, which in turn drives the four sleeves to move up and down synchronously, which in turn drives the upper rubber seat to move up and down. This makes it easy to adjust the distance between the two transmission rollers and the distance between the two extrusion rollers synchronously, which can adapt to materials of different thicknesses.

[0015] 2. The four connecting pins engage with the four connecting slots to facilitate initial positioning of the preheating structure. The four limiting springs engage with the four limiting slots to further position the preheating structure. The installation of several heating elements facilitates initial preheating of the material, which is convenient for subsequent operations. By pulling the mounting plate with a large force, the two limiting springs can be separated from the two limiting slots, which facilitates quick disassembly and maintenance of the preheating structure.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figure 1-5This utility model provides a glue applicator with a low-energy-consumption hot melt adhesive rapid preheating structure, including a lower glue base 1. Two mounting seats 2 are fixedly arranged on both sides of the lower glue base 1. A transmission seat 3 is fixedly arranged on the top between the four mounting seats 2. Lead screws 7 are rotatably arranged on the bottom inner side of each of the four mounting seats 2. The top ends of the four lead screws 7 extend into the interior of the transmission seat 3 and are fixedly connected to transmission wheels 8. A belt 9 is driven between the four transmission wheels 8. Sleeves 10 are threaded onto the middle of the surface of each of the four lead screws 7. Moving blocks 11 are fixedly arranged on one side of each of the four sleeves 10. An upper glue base 4 is fixedly arranged between the four moving blocks 11. An installation hole is opened at the middle of the bottom end of the upper glue base 4 and the middle of the top end of the lower glue base 1. The two mounting slots 13 each have a mounting plate 14 that engages with each other. Several heating tubes 15 are fixedly installed on opposite sides of the two mounting plates 14. The motor 22 drives the drive gear 23 to rotate. Since the drive gear 23 meshes with the driven gear 21, it drives one of the lead screws 7 to rotate. Since the four transmission wheels 8 are connected by a belt 9, the four transmission wheels 8 rotate synchronously, which in turn drives the four lead screws 7 to rotate synchronously, which in turn drives the four sleeves 10 to move up and down synchronously, which in turn drives the upper rubber seat 4 to move up and down. This allows for synchronous adjustment of the distance between the two transmission rollers 5 and the distance between the two extrusion rollers 6, which can accommodate materials of different thicknesses.

[0024] A driven gear 21 is fixedly installed on the bottom of the surface of one of the lead screws 7, and a motor 22 is fixedly installed on the bottom of one side of one of the mounting seats 2. The output end of the motor 22 extends into the interior of one of the mounting seats 2 and is fixedly connected to a driving gear 23. The driving gear 23 meshes with the driven gear 21. A moving groove 12 is opened in the middle of the inner side of each of the four mounting seats 2. The four moving grooves 12 are slidably connected to the four moving blocks 11 respectively. A rotating hole 24 is opened at the connection between the four mounting seats 2 and the transmission seat 3. The eight rotating holes 24 are rotatably connected to the four lead screws 7 respectively.

[0025] In use, the motor 22 drives the drive gear 23 to rotate. Since the drive gear 23 meshes with the driven gear 21, it drives one of the lead screws 7 to rotate. Since the four transmission wheels 8 are connected by a belt 9, the four transmission wheels 8 rotate synchronously, which in turn drives the four lead screws 7 to rotate synchronously. The four moving slots 12 facilitate the stable movement of the four moving blocks 11, and the four rotating holes 24 facilitate the stable rotation of the four lead screws 7.

[0026] A drive roller 5 is provided on one side of the bottom end of the upper glue seat 4 and one side of the top end of the lower glue seat 1. A squeeze roller 6 is provided on the side of the bottom end of the upper glue seat 4 away from the drive roller 5 and the side of the top end of the lower glue seat 1 away from the drive roller 5. A connecting slot 16 is provided at the connection between the two mounting slots 13 and the two mounting plates 14. A connecting pin 17 is engaged inside each of the four connecting slots 16. The four connecting pins 17 are fixedly connected to the two mounting plates 14. An installation slot 18 is provided on one side of each of the four connecting pins 17. A limiting spring piece 19 is fixedly provided inside each of the four installation slots 18. A limiting groove 20 is provided on one side of the inner wall of each of the four connecting slots 16. The four limiting spring pieces 19 are engaged with the four limiting grooves 20 respectively.

[0027] In use, the two drive rollers 5 facilitate the conveying of materials, the four connecting pins 17 engage with the four connecting slots 16 to facilitate the initial positioning of the preheating structure, and the four limiting springs 19 engage with the four limiting slots 20 to facilitate the further positioning of the preheating structure.

[0028] In this embodiment, the motor 22 drives the drive gear 23 to rotate. Since the drive gear 23 meshes with the driven gear 21, it drives one of the lead screws 7 to rotate. Because a belt 9 is installed between the four transmission wheels 8, the four transmission wheels 8 rotate synchronously, which in turn drives the four lead screws 7 to rotate synchronously, causing the four sleeves 10 to move up and down synchronously. This, in turn, causes the upper rubber seat 4 to move up and down, facilitating synchronous adjustment of the distance between the two transmission rollers 5 and the distance between the two extrusion rollers 6, thus adapting to different thicknesses. When using materials of a certain temperature, the four connecting pins 17 engage with the four connecting slots 16 to facilitate initial positioning of the preheating structure. The four limiting springs 19 engage with the four limiting grooves 20 to further position the preheating structure. The arrangement of several heating tubes 15 facilitates initial preheating of the material, which is convenient for subsequent operations. By pulling the mounting plate 14 with a large force, the two limiting springs 19 are separated from the two limiting grooves 20, which facilitates quick disassembly and maintenance of the preheating structure.
