[0032] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0033] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0034] Example 1:

[0035] like Figure 1-5 As shown, a constant temperature and humidity structure for a roller glue machine includes a housing 1, a cooling component is fixedly connected to the top of the housing 1, and a cold air jet component 5 is fixedly connected to one end of the cooling component.

[0036] The other end of the cooling component is connected to the fabric guiding unit and the adhesive coating unit through the first pipe group and the second pipe group;

[0037] The first pipe group includes multiple first air outlet pipes 4, each of which is fixedly connected to the fabric guiding unit via a rotary joint 10; the second pipe group includes at least one second air outlet pipe 26, which is fixedly connected to the adhesive application unit.

[0038] The fabric guiding unit includes: multiple feeding rollers 9, one end of each feeding roller 9 being fixedly connected to each of the rotary joints 10; the adhesive coating unit includes: a second air outlet pipe 26 being fixedly connected to a diversion pipe 12, and two rotary joints 13 being fixedly connected to the two diversion ports of the diversion pipe 12, and glue rollers 14 being fixedly connected to the movable ends of the rotary joints 13, forming a fabric channel between the two glue rollers 14.

[0039] In this embodiment, the cooling component is used to cool the fabric guiding unit and the adhesive coating unit. The fabric guiding unit is used to guide and tension the fabric and guide it into the adhesive coating unit for adhesive coating. During this process, the cooling component can deliver cooled gas to the inside of the feed roller 9 and the adhesive roller 14 through the pipes in the first and second pipe groups. When the feed roller 9 and the adhesive roller 14 come into contact with the fabric, they are cooled, thereby cooling the fabric.

[0040] In this embodiment, the cooling component includes an air inlet pipe 2 and a cooling component 3. One end of the air inlet pipe 2 is fixedly connected to the top of the box 1 and communicates with the inside of the box 1 through an air intake 8, and the other end is fixedly connected to the air inlet of the cooling component 3.

[0041] The air outlet of the cooling component 3 is connected to both the first air outlet pipe 4 and the second air outlet pipe 26 in the first pipe group and the second pipe group.

[0042] Specifically, see the main pipe 27 located at the top of the box 1 and connected to the air outlet of the cooling component 3. One end of the main pipe 27 is connected to the air outlet, and the other end forms a strip-shaped passage (fixed inside the box 1). This strip-shaped passage is connected to the first air outlet pipe 4 and the second air outlet pipe 26 in the first pipe group and the second pipe group.

[0043] Furthermore, the fabric guiding unit includes three triangularly arranged feeding rollers 9, and the glue coating unit includes a glue roller 14. The feeding rollers 9 and the glue roller 14 are hollow inside. When feeding, the feeding rollers 9 can keep the fabric entering the device taut to prevent wrinkles. The cooling component 3 is a cooling and dehumidifying machine, which can be air-cooled or liquid-cooled. It can achieve constant temperature and humidity by cooling the air passing through it. The gas enters from the air inlet pipe 2 and exits from the air outlet pipe 4. The low-temperature gas exiting the device enters the feeding rollers 9 and the glue roller 14 through the pipes connected by the rotary joint 10 and the rotary joint 2 13, respectively, and cools the fabric that is in contact with the outside of the feeding rollers 9 and the glue roller 14 from the inside. At the same time, the low-temperature gas can be sprayed into the device from both sides through the nozzle of the cold air jet 5, which is directly connected to the main pipe 7, so that the fabric can be cooled from the inside and outside.

[0044] The air intake 8 is located on both sides of the top of the box 1. By communicating with the air inlet, it can absorb the hot air above the box 1 during the start-up of the cooling component 3.

[0045] In this embodiment, the rubber roller 14 is hollow inside and is fixedly connected with a plurality of spaced heat dissipation fins 23. Each heat dissipation fin 23 is provided with a cooling pipe 22. One end of the cooling pipe 22 is fixedly connected to the movable end of the rotary joint 13 and communicates with one port of the diverter 12. The curved cooling pipe 22 can prolong the time that the gas passes through the rubber roller 14 and improve the cooling effect from the inside through the plurality of heat dissipation fins 23.

[0046] In this embodiment, the end of the feed roller 9 away from the first air outlet pipe 4 is also connected to an exhaust pipe 11 through another rotary joint 10. In order to ensure the stable rotation of the feed roller 9, rotary joints 10 are provided on both sides of the feed roller 9, one end of which is connected to the exhaust pipe 11, and the other end is used to connect to the first air outlet pipe 4.

[0047] The end of the rubber roller 14 away from the second air outlet pipe 26 is also connected to the second exhaust pipe 19 via another diverter pipe 12 and the second rotary joint 13. In order to ensure the stable rotation of the rubber roller 14, both ends of the rubber roller 14 are also provided with diverter pipes 12 and rotary joints 13. One diverter pipe 12 is connected to the second air outlet pipe 26, and the other is connected to the second exhaust pipe 19. That is, the first exhaust pipe 11 and the second exhaust pipe 19 are respectively connected to the feed roller 9 and the rubber roller 14. Accordingly, the gas inside the feed roller 9 and the rubber roller 14 can be discharged through the corresponding first exhaust pipe 11 and second exhaust pipe 19 on the other side.

[0048] In this embodiment, a rubber roller bracket 7 is fixedly connected inside the housing 1, and a drive motor 16 is fixedly connected to one end of the rubber roller bracket 7; the ends of the two rubber rollers 14 near the second air outlet pipe 26 both penetrate the side wall of the rubber roller bracket 7 and are fixedly connected to a set of synchronous gears 15 and synchronous pulleys 17; the two sets of synchronous gears 15 are meshed with each other, and one end of one of the synchronous pulleys 17 is connected to the power output end of the drive motor 16 through a synchronous belt 18. The drive motor 16 can drive the rubber rollers 14 on both sides to rotate synchronously through the synchronous belt 18 and the synchronous gears 15 to apply glue.

[0049] In this embodiment, a feeding bracket 25 is fixedly connected inside the housing 1. The feeding bracket 25 is used to support the rotation of the feeding roller 9. As can be seen from the above description of the fabric guiding unit, the feeding roller 9 in the fabric guiding unit needs to be arranged in a triangular shape, so a corresponding feeding bracket 25 is needed to provide support for it.

[0050] In this embodiment: the feed roller 9 and the rubber roller 14 are hollow inside. When feeding, the feed roller 9 can keep the fabric entering the device taut to prevent wrinkles. It can also achieve constant temperature and humidity by cooling the air passing through the feed roller 9 and the rubber roller 14. The gas absorbed by the air inlet 8 enters through the air inlet pipe 2 and exits through the air outlet pipe 4. The low-temperature gas exits enters the feed roller 9 and the rubber roller 14 through the first air outlet pipe 4 and the second air outlet pipe 26 connected by the rotary joint 10 and the rotary joint 23, respectively. It cools the fabric that is in contact with the feed roller 9 and the rubber roller 14 from the inside. At the same time, the cold air jet 5 can spray low-temperature gas into the device from both sides, which can cool the fabric from the inside and outside.

[0051] The curved cooling pipe 22 can prolong the time that the gas passes through the rubber roller 14, and the cooling effect from the inside is improved by multiple heat dissipation fins 23. The drive motor 16 can drive the rubber rollers 14 on both sides to rotate synchronously through the synchronous belt 18 and the synchronous gear 15. The fabric enters from the opening on one side of the box 1, is guided and tensioned by multiple feed rollers 9, and at the same time, the low temperature air passing through the inside of the feed rollers 9 is used to pre-cool the fabric. Then the fabric is squeezed and coated with glue between the two rubber rollers 14, and after the glue is coated, it is removed from the device through the groove on one side of the rubber roller support 7 and the box 1.

[0052] Example 2:

[0053] A constant temperature and humidity structure for a roller glue machine is provided. This embodiment is based on Embodiment 1 with the following improvements, such as... Figure 1-5 As shown,

[0054] In this embodiment, a glue tank 6 is fixedly connected to one side of the box 1. A glue spray nozzle 21 is fixedly connected to one end of the glue tank 6 through a connecting pipe. One end of the glue spray nozzle 21 is fixedly connected to the inside of the glue roller bracket 7 and is located above the glue roller 14. Multiple heat dissipation fins 24 are fixedly connected to the periphery of the connecting pipe between the glue spray nozzle 21 and the glue tank 6. The glue spray nozzle 21 is a flat nozzle, which can spray glue more evenly. At the same time, multiple heat dissipation fins 24 are installed on the pipe on one side of the glue spray nozzle 21, which can cool down the gel that is about to be sprayed, resulting in higher cooling efficiency.

[0055] In this embodiment, a temperature and humidity monitoring component 20 is fixedly connected to one end of the glue roller bracket 7. This component is used to collect the temperature around the fabric during the glue coating process and generate a temperature signal, which can better monitor the temperature near the fabric being coated.
