Abstract
Description
Technical Field
[0001] This application relates to the field of hot melt adhesive machines, and more particularly to a double-roller hot melt adhesive machine. Background Technology
[0002] The lining that needs to be glued to the clothing fabric is first pressed flat by a hot melt adhesive machine, and then taken outside to be pressed onto the clothing. This process requires the use of a hot melt adhesive machine for pressing.
[0003] Existing hot melt bonding machines are usually set to operate with a single pressure roller, which is insufficient in terms of compaction during pressing and cannot effectively press the lining fabric flat. In addition, the height of the existing pressure roller is not easy to adjust, and it cannot handle the pressing operation of lining fabrics of different thicknesses. Therefore, this application proposes a double pressure roller hot melt bonding machine. Utility Model Content

[0006] In a preferred embodiment, two supports are symmetrically installed on the bottom of the operating table, and the two supports are symmetrically arranged on both sides of the bottom of the operating table.
[0007] By adopting the above technical solution, the device can be stably supported, ensuring the stability of the operating platform during operation and preventing it from easily shaking.
[0008] In a preferred embodiment, a temperature controller is installed on the outside of the operating table, and heating rods are installed inside both the first and second pressure rollers, with both heating rods electrically connected to the temperature controller.
[0009] By adopting the above technical solution, the temperature generated during the operation of the heating rod can be precisely controlled, thereby achieving stable heat transfer and ensuring the viscosity of the material adhesion, thus preventing damage to the material.
[0010] In a preferred embodiment, a fixing plate is fixedly installed on the outside of the motor, and the side of the motor away from the drive gear is fixedly connected to the fixing plate.
[0011] By adopting the above technical solution, it can be used to position the motor, ensuring the stability of the motor during operation and preventing it from easily shaking during operation.
[0012] In a preferred embodiment, a second cylinder is fixedly installed on the top of the frame, and a scraper is fixedly connected to the power output shaft of the second cylinder through the frame. The scraper is located in the middle of the first and second pressure rollers, and the two sides of the scraper are arc-shaped and fit against the outer edges of the first and second pressure rollers.
[0013] By adopting the above technical solution, the drive cylinder 2 can drive the scraper to move up and down, thereby moving the scraper to a high position during the operation of pressure roller 1 and pressure roller 2 so as not to contact the outer edge of pressure roller 1 and transmission gear 2. At the end of the operation, the scraper can contact pressure roller 1 and pressure roller 2 respectively to scrape off the impurities adhering to the surface of pressure roller 1 and pressure roller 2, thereby realizing automated cleaning.

[0015] By adopting the above technical solution, the stability of transmission gear one, driven gear, driving gear, motor and transmission gear two during rotation can be guaranteed, ensuring that they will not easily deviate from their positions.
[0016] In a preferred embodiment, there are two cylinders, and the two cylinders are symmetrically arranged on the inner top of the protective cover.
[0017] By adopting the above technical solution, two cylinders can be driven to move the frame up and down synchronously, adjusting the distance between the bottom of the first and second pressure rollers and the top of the operating table, thus facilitating the roll pressing and hot melting operation of materials of different thicknesses.
[0018] The beneficial effects of this application are:
[0019] This dual-roller hot melt bonding machine can achieve synchronous operation of two rollers to repeatedly squeeze the lining fabric by setting roller one and roller two, ensuring the compactness and flatness of the bonding. At the same time, it can drive two cylinders to move the frame up and down synchronously, and adjust the distance between the bottom of roller one and roller two and the top of the operating table, thus facilitating the roller pressing and hot melt operation of materials of different thicknesses.
[0020] This dual-roller hot melt bonding machine uses a second-stage cylinder to drive a scraper that moves downwards to contact the first and second rollers, thereby scraping away impurities adhering to the surfaces of the first and second rollers and achieving automated cleaning.

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.
[0027] Reference Figure 1-4 A double-roller hot melt bonding machine includes an operating table 1. A protective cover 4 is fixedly installed on the top of the operating table 1. A cylinder 5 is installed on the inner top of the protective cover 4. A frame 6 is fixedly connected to the power output shaft of the cylinder 5. One side of a pressure roller 7 and a pressure roller 2 15 are rotatably connected to the inner wall of the frame 6. A transmission gear 8 and a transmission gear 2 16 are fixedly installed on the other side of the pressure roller 7 and the pressure roller 2 15, respectively. A driven gear 9 meshes in the middle of the transmission gear 8 and the transmission gear 2 16. A driving gear 10 meshes at the top of the driven gear 9. The power output shaft of a motor 11 is fixedly connected to the outer side of the driving gear 10.
[0028] See Figure 1 Two supports 3 are symmetrically installed on the bottom of the operating table 1, and the two supports 3 are symmetrically arranged on both sides of the bottom of the operating table 1, so that they can be used to stably support the device, ensure the stability of the operating table 1 during operation, and ensure that it will not easily shake.
[0029] See Figure 1 and Figure 4A temperature controller 2 is installed on the outside of the operating table 1. Heating rods are installed inside the pressure roller 7 and the pressure roller 15, and both heating rods are electrically connected to the temperature controller 2, so that the temperature generated by the heating rods during operation can be precisely controlled, thereby achieving stable heat transfer and ensuring the viscosity of the material adhesion, and further preventing damage to the material.
[0030] See Figure 4 A fixing plate 12 is fixedly installed on the outside of the motor 11. The side of the motor 11 away from the drive gear 10 is fixedly connected to the fixing plate 12, which can be used to position the motor 11, ensure the stability of the motor 11 during operation, and ensure that it will not easily shake during operation.
[0031] See Figure 3 and Figure 4 A second cylinder 13 is fixedly installed on the top of the frame 6, and a scraper 14 is fixedly connected to the power output shaft of the second cylinder 13 through the frame 6. The scraper 14 is located in the middle of the first pressure roller 7 and the second pressure roller 15. The two sides of the scraper 14 are arc-shaped and fit against the outer edges of the first pressure roller 7 and the second pressure roller 15, so that the second cylinder 13 can drive the scraper 14 to move up and down. In this way, when the first pressure roller 7 and the second pressure roller 15 are working, the scraper 14 can be moved to a high position so as not to contact the outer edges of the first pressure roller 7 and the second transmission gear 16. At the end of the operation, the scraper 14 can be used to contact the first pressure roller 7 and the second pressure roller 15 respectively to scrape off the impurities adhering to the surface of the first pressure roller 7 and the second pressure roller 15, thereby realizing automated cleaning.

[0033] See Figure 2 and Figure 3 There are two cylinders 5, and the two cylinders 5 are symmetrically arranged on the inner top of the protective cover 4, so that the two cylinders 5 can drive the frame 6 to move up and down synchronously, adjust the distance between the bottom of the pressure roller 7 and the pressure roller 15 and the top of the operating table 1, and thus facilitate the roller pressing and hot melting operation of materials of different thicknesses.
[0034] Working principle:
[0035] First, the material to be processed can be placed on the top of the operating table 1. Then, the cylinder 5 can be driven to move the frame 6 downward until the pressure roller 7 and pressure roller 2 15 contact the top of the material. Then, the motor 11 can be driven to rotate the drive gear 10. Then, the driven gear 9 can be used to drive the transmission gear 8 and transmission gear 2 16 to rotate, so as to drive the pressure roller 7 and pressure roller 2 15 to rotate synchronously and perform roller pressing on the material to ensure the compactness of the pressing.
[0036] After the operation is completed, the cylinder 13 can be driven to move the scraper 14 downward to contact the pressure roller 7 and the pressure roller 15 respectively, thereby scraping off the impurities adhering to the surface of the pressure roller 7 and the pressure roller 15, thus realizing automated cleaning.
