Description

A roller coating heating and gluing device Technical Field

[0001] This utility model relates to the field of roller coating technology, and in particular to a roller coating heating and coating device. Background Technology

[0002] Roller coating refers to the process of wrapping rubber or other elastic materials onto the outer surface of a roller's metal core using a specific process. This forms a wear-resistant, corrosion-resistant, and elastic coating on the metal substrate, significantly improving the roller's physical properties. The coating effectively buffers pressure, reduces the coefficient of friction, and enhances resistance to chemicals, thereby extending the roller's service life. This technology is widely used in industries such as printing, papermaking, metallurgy, and logistics transportation. To accelerate the curing of the coating and shorten the process cycle, a heated coating device is required.

[0003] However, in traditional gluing devices, the contact between the film and the roller is mostly unidirectional feeding or unidirectional rotation of the roller for rigid bonding. The film feeding speed and the roller rotation speed lack dynamic matching. The two speeds are not coordinated, and the film will be stretched and deformed due to uneven force, sudden friction, or local stress concentration, which will affect the coating quality. In addition, insufficient and uncoordinated preheating of the roller and the film is not conducive to good adhesion of the film and affects the coating effect. There are certain drawbacks in the use process.

[0004] In view of the above, this utility model is hereby proposed. Summary of the Invention

[0005] To overcome the technical defects of the existing technology, this utility model provides a roller coating heating and gluing device, which has the effect of avoiding the stretching of the rubber sheet, making the coating more uniform, improving the coating quality and efficiency, and at the same time, it can achieve efficient heating and temperature uniformity to ensure the coating effect.

[0006] The technical solution adopted by this utility model is as follows: it includes a U-shaped mounting base and a roller body. The elastic pin-type rotary drive assembly is mounted on the U-shaped mounting base. The roller body is rotatably mounted on the U-shaped mounting base through the elastic pin-type rotary drive assembly. The connecting strip is fixedly mounted on the inner wall of the U-shaped mounting base. A limiting groove is formed on the connecting strip. The propulsion drive assembly is installed in the limiting groove. The heat-conducting placement plate is mounted on the propulsion drive assembly. The film is placed on the heat-conducting placement plate. One end of the propulsion drive assembly is connected to the elastic pin-type rotary drive assembly through the synchronous connection assembly. The steam box is fixedly inserted into the U-shaped mounting base. The steam box is connected to a high-temperature steam pipe through the air inlet connector. The steam box is located below the heat-conducting placement plate. The upper heating part is fixedly mounted on the top of the U-shaped mounting base. The upper heating part is connected to the steam box through the connecting pipe.

[0007] Preferably, in order to enable the rotating connecting cylinder to drive the roller body to rotate via the hexagonal pin, the control elastic pin-type rotary drive assembly includes the rotating connecting cylinder and the L-shaped connecting seat. The hexagonal pin is inserted into the rotating connecting cylinder, and the hexagonal pin is elastically connected to the inner wall of one end of the rotating connecting cylinder via the clamping spring. One end of the hexagonal pin is inserted into a pre-drilled hexagonal slot on the roller body.

[0008] Preferably, in order to enable the rotating connecting cylinder to rotate by controlling the drive motor, the drive motor is fixedly installed on the side wall of the L-shaped connecting seat, and one end of the rotating connecting cylinder is fixedly connected to the output shaft of the drive motor.

[0009] Preferably, in order to enable the drive threaded rod to rotate stably in the limiting slide groove via the rotary joint, the propulsion drive assembly includes the drive threaded rod, which is rotatably mounted on the inner wall of one end of the limiting slide groove via the rotary joint.

[0010] Preferably, in order to control the rotation of the driven bevel gear so that the drive threaded rod can rotate, the driven bevel gear is fixedly mounted on one end of the drive threaded rod.

[0011] Preferably, in order to enable the threaded slider to slide in the limiting groove by controlling the rotation of the drive threaded rod, the threaded slider is mounted on the drive threaded rod, the threaded slider is slidably engaged in the limiting groove, and the heat-conducting placement plate is fixed on the threaded slider.

[0012] Preferably, in order for the rotating connecting cylinder to drive the synchronous connecting shaft to rotate via the synchronous belt, the synchronous connecting assembly includes the extension block, one end of which is rotatably mounted with the synchronous connecting shaft, and the synchronous connecting shaft is connected to the rotating connecting cylinder via the synchronous belt.

[0013] Preferably, in order for the synchronous connecting shaft to drive the driven bevel gear to rotate via the driving bevel gear, the driving bevel gear is fixedly installed at one end of the synchronous connecting shaft, and the driving bevel gear is meshed with the driven bevel gear.

[0014] The beneficial effects of this utility model are as follows: By linking the elastic pin-type rotary drive assembly and the synchronous connection assembly, the roller body rotates and the drive assembly pushes the film closer to achieve coating and gluing. The rotation of the roller body and the movement of the film are coordinated to effectively avoid film pulling, making the coating more uniform and improving the coating quality and efficiency. At the same time, the steam box and the upper heating part are used to heat the heat-conducting plate and the roller body, achieving efficient heating and uniform temperature, ensuring the coating effect.

[0021] The present invention will be further described below with reference to the accompanying drawings:

[0022] As shown in Figures 1-5, this embodiment provides a roller coating heating and gluing device, including a U-shaped mounting base 1 and a roller body 2. A flexible pin-type rotary drive assembly 3 is mounted on the U-shaped mounting base 1. The roller body 2 is rotatably mounted on the U-shaped mounting base 1 via the flexible pin-type rotary drive assembly 3. A connecting strip 4 is fixedly mounted on the inner wall of the U-shaped mounting base 1. A limiting groove is formed on the connecting strip 4, and a propulsion drive assembly 5 is installed in the limiting groove. A heat-conducting placement plate 6 is mounted on the propulsion drive assembly 5. The device includes a film 7, a propulsion drive assembly 5, and a U-shaped mounting base 1. One end of the propulsion drive assembly 5 is connected to the elastic pin-type rotary drive assembly 3 via a synchronous connection assembly 8. A steam box 9 is fixedly inserted into the U-shaped mounting base 1. The steam box 9 is connected to a high-temperature steam pipe via an air inlet connector 10 and is located below the heat-conducting placement plate 6. An upper heating part 11 is fixedly installed on the top of the U-shaped mounting base 1, and the upper heating part 11 is connected to the steam box 9 via a connecting pipe 12. In use, the roller body 2 is first installed on the U-shaped mounting base via the elastic pin-type rotary drive assembly 3. The high-temperature steam pipe is connected via the air inlet connector 10, causing the steam box 9 to heat up. The heat is transferred to the heat-conducting placement plate 6, and the upper heating part 11 preheats the roller body 2 via the connecting pipe 12. Activating the flexible pin-type rotary drive assembly 3 allows the roller body 2 to rotate while simultaneously being driven by the synchronous connection assembly 8. This drives the drive assembly 5 to push the heat-conducting placement plate 6 and the film 7 closer to the roller body 2, causing the roller body 2 to adhere to one top end of the film 7. As the roller body 2 rotates, the roller body is coated with adhesive. The rotation of the roller body 2, combined with the movement of the film 7, prevents the film 7 from being stretched during the coating process, resulting in more uniform coating.

[0023] As a technical optimization of this utility model, as shown in Figure 4, the elastic pin-type rotary drive assembly 3 includes a rotary connecting cylinder 301 and an L-shaped connecting seat 302. A hexagonal pin 303 is inserted into the rotary connecting cylinder 301. The hexagonal pin 303 is elastically connected to the inner wall of one end of the rotary connecting cylinder 301 through a clamping spring 304. One end of the hexagonal pin 303 is inserted into a pre-opened hexagonal slot on the roller body 2. A drive motor 305 is fixedly installed on the side wall of the L-shaped connecting seat 302. One end of the rotary connecting cylinder 301 is fixedly connected to the output shaft of the drive motor 305. In use, the rotary connecting cylinder 301 is aligned with the roller body 2, so that the hexagonal pin 303 is elastically inserted into the pre-opened hexagonal slot of the roller body 2 under the action of the clamping spring 304, which facilitates the installation of the roller body 2 and achieves a stable insertion and positioning. Next, the drive motor 305 on the L-shaped connecting seat 302 is started. The output shaft of the drive motor 305 drives the rotating connecting cylinder 301 to rotate synchronously, thereby driving the roller body 2 connected to it to rotate stably.

[0024] As a technical optimization of this utility model, as shown in Figures 2 and 3, the propulsion drive assembly 5 includes a drive threaded rod 501, which is rotatably mounted on the inner wall of one end of the limiting slide groove via a rotary joint 502. A driven bevel gear 503 is fixedly mounted on one end of the drive threaded rod 501, and a threaded slider 504 is mounted on the drive threaded rod 501. The threaded slider 504 is slidably engaged in the limiting slide groove, and a heat-conducting plate 6 is fixed on the threaded slider 504. The synchronous connection assembly 8 includes an extension block 801, with a synchronous connection shaft 802 rotatably mounted on one end of the extension block 801. The synchronous connection shaft 802 is connected to the rotating connecting cylinder 301 via a synchronous belt 803, and a drive bevel gear 804 is fixedly mounted on one end of the synchronous connection shaft 802. The drive bevel gear 804 meshes with the driven bevel gear 503. In use, the rotating connecting cylinder 301 rotates, which drives the synchronous connection shaft 802 to rotate via the synchronous belt 803, and the drive bevel gear 804 on the synchronous connection shaft 802 rotates accordingly. Because the driving bevel gear 804 meshes with the driven bevel gear 503 at one end of the driving threaded rod 501, the threaded rod 501 is driven to rotate. The threaded slider 504 is constrained by the limiting groove and slides along its axial direction under the drive of the threaded rod, which drives the heat-conducting plate 6 and the film 7 fixed on it to be pushed towards the roller body 2, so that the film 7 contacts the roller body 2 and cooperates with the rotation of the roller body 2 to complete the coating.

Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention.
