Description

Technical Field

[0001] This utility model relates to the field of laser transfer paper production technology, specifically a drying device for laser transfer paper production. Background Technology

[0002] Laser transfer paper, also known as holographic transfer paper or hot stamping transfer film, is a special printing material primarily used to achieve high-quality decorative effects on various substrates. It typically consists of a multi-layered structure, including a base film layer, a laser pattern layer, a release layer, and a hot melt adhesive layer. This material can transfer laser patterns onto the surface of a target object under heat, and is commonly used in packaging, labeling, card making, and other fields to enhance the visual appeal of products.

[0003] Based on the above, the inventors have discovered the following problems: the current drying equipment for laser transfer paper production has a relatively complex structure, usually consisting of a drying component and a cooling component, which occupies a large area and is inconvenient to use.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a drying device for laser transfer paper production, in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this invention is to provide a drying device for laser transfer paper production to solve the problems mentioned in the background art.

[0006] A drying device for laser transfer paper production includes a drying assembly. The drying assembly includes a housing. A heat insulation plate is fixedly installed at the top center of the inner side of the housing. The heat insulation plate divides the interior of the housing into a cooling chamber and a drying chamber. A paper outlet is provided at the top of the housing facing the cooling chamber, and a paper inlet is provided at the bottom of the housing facing the drying chamber. Sealing rollers are rotatably connected to the top and bottom of the inner side of the paper inlet. Moving roller assemblies are provided on the inner side of both the paper inlet and the paper outlet facing the housing. Five infrared heaters are fixedly installed in the middle of the inner side of the drying chamber, and an exhaust fan is fixedly installed at the top of the drying chamber.

[0007] By adopting the above technical solution, the heat insulation plate facilitates the separation of the cooling chamber and the drying chamber, preventing the infrared heater inside the drying chamber from heating the cooling chamber. The paper outlet facilitates the exit of the laser transfer paper after drying and cooling. The paper inlet facilitates the entry of the laser transfer paper to be dried into the drying device. The sealing roller facilitates sealing of the paper inlet, preventing air from entering the drying chamber without obstructing the laser transfer paper from entering the drying device. The moving roller assembly facilitates the movement of the laser transfer paper in and out of the device. The device is designed to be opened and can tighten the laser transfer paper inside, facilitating its drying and cooling. An infrared heater is installed to heat and dry the laser transfer paper inside the drying chamber. An exhaust fan is fixedly installed at the top of the drying chamber to remove steam or volatile organic compounds generated during the drying process. This fan also creates negative pressure inside the drying chamber, drawing external airflow from the paper outlet through the cooling chamber into the drying chamber, thereby increasing the airflow speed inside the cooling chamber and cooling the dried laser transfer paper.

[0008] Furthermore, the exhaust fan is located at the top of the end of the outer casing facing the paper inlet, and an exhaust port is fixedly installed on the top of the exhaust fan.

[0009] By adopting the above technical solution and setting the exhaust interface, it is easy to connect to external pipelines, which facilitates the recovery and treatment of steam or volatile organic compounds generated during the drying process of the device, thus avoiding pollution of the external environment.

[0010] Furthermore, five first guide rollers are rotatably connected inside the drying chamber, and the five first guide rollers are arranged alternately at the bottom and top of the infrared heater.

[0011] By adopting the above technical solution, the first guide rollers are arranged such that two first guide rollers are set at the top of the infrared heater and three first guide rollers are set at the bottom of the infrared heater. This facilitates the first guide rollers to form an "M"-shaped structure of the laser transfer paper inside the drying chamber and to wrap around the outside of the infrared heater, thereby extending the path of the laser transfer paper inside the drying chamber and enabling the device to fully dry the laser transfer paper.

[0012] Furthermore, two second guide rollers are rotatably connected inside the cooling chamber, and a channel is opened at the bottom end of the heat insulation plate.

[0013] By adopting the above technical solution, the setting of the second guide roller facilitates the guidance of the dried laser transfer paper from the channel at the bottom of the heat insulation plate into the cooling chamber for cooling.

[0014] Furthermore, the moving roller assembly includes a driving roller and a driven roller, both of which are disposed inside the housing and are rotatably connected to the housing.

[0015] By adopting the above technical solution, the arrangement of the active roller and the driven roller facilitates the rotation of the active roller and the driven roller to drive the laser transfer paper into and out of the device.

[0016] Furthermore, a drive gear is fixedly installed at one end of the drive roller, and a pulley is fixedly installed on one side of the drive gear. Both the drive gear and the pulley are located on the outside of the housing.

[0017] By adopting the above technical solution, with both the drive gear and the pulley located on the outside of the housing, it is convenient for the external drive device to use a transmission belt sleeved on the outside of the pulley to drive the drive roller to rotate.

[0018] Furthermore, a driven gear is fixedly installed at one end of the driven roller. The driven gear is located on the outside of the housing and is meshed with the driving gear.

[0019] By adopting the above technical solution, the driven gear and the driving gear are meshed together, which facilitates the synchronous rotation of the driving roller and the driven roller.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: The heat insulation plate facilitates the separation of the cooling chamber and the drying chamber, preventing the infrared heater inside the drying chamber from heating the cooling chamber. The paper outlet facilitates the exit of the laser transfer paper after drying and cooling. The paper inlet facilitates the entry of the laser transfer paper to be dried into the drying device. The sealing roller facilitates sealing of the paper inlet, preventing air from entering the drying chamber without obstructing the entry of the laser transfer paper into the drying device. The moving roller assembly facilitates the movement of the laser transfer paper into and out of the device and keeps the laser transfer paper stretched inside the device. This design features a compact structure that facilitates the drying and cooling of laser transfer paper. An infrared heater allows for efficient heating and drying of the laser transfer paper within the drying chamber. An exhaust fan, fixed to the top of the drying chamber, removes steam or volatile organic compounds generated during the drying process and creates negative pressure within the chamber. This draws external airflow from the paper outlet through the cooling chamber into the drying chamber, increasing airflow speed and effectively cooling the dried laser transfer paper. This invention provides thorough drying and cooling of laser transfer paper, and its compact structure and small footprint make it highly practical. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-4This utility model provides a technical solution: a drying device for laser transfer paper production, including a drying component 101. The drying component 101 includes a housing 10101, and a heat insulation plate 10109 is fixedly installed at the top center of the inner side of the housing 10101. The heat insulation plate 10109 facilitates the separation of the cooling chamber 10110 and the drying chamber 10111, preventing the infrared heater 10107 inside the drying chamber 10111 from heating the cooling chamber 10110. The heat insulation plate 10109 divides the interior of the housing 10101 into the cooling chamber 10110 and the drying chamber 10111. A paper outlet 10103 is provided at the top of one end facing the cooling chamber 10110. The paper outlet 10103 facilitates the exit of the laser transfer paper after drying and cooling from the device. A paper inlet 10102 is provided at the bottom of one end of the outer casing 10101 facing the drying chamber 10111. The paper inlet 10102 facilitates the entry of the laser transfer paper to be dried into the device for drying. Sealing rollers 10106 are rotatably connected to the top and bottom of the inner side of the paper inlet 10102. The sealing rollers 10106 facilitate the sealing of the paper inlet 10102, preventing air from entering the drying chamber through the paper inlet 10102. 10111, and does not obstruct the entry of the laser transfer paper to be dried into the drying device, both the paper inlet 10102 and the paper outlet 10103 are equipped with moving roller assemblies 102 on the side facing the inside of the outer shell 10101. The moving roller assemblies 102 facilitate the entry and exit of the laser transfer paper into and out of the device, and can tighten the laser transfer paper inside the device, which is convenient for drying and cooling the laser transfer paper. Five infrared heaters 10107 are fixedly installed in the middle of the inner side of the drying chamber 10111. The infrared heaters 10107 facilitate the laser transfer paper inside the drying chamber 10111. The paper is heated and dried. An exhaust fan 10104 is fixedly installed on the top of the drying chamber 10111. The exhaust fan 10104 is fixedly installed on the top of the drying chamber 10111 to facilitate the operation of the exhaust fan 10104 to remove the steam or volatile organic compounds generated inside the drying chamber 10111 during the drying process. It can also create a negative pressure inside the drying chamber 10111, which draws external airflow from the paper outlet 10103 and flows through the cooling chamber 10110 into the drying chamber 10111, thereby increasing the airflow speed inside the cooling chamber 10110 and cooling the dried laser transfer paper inside the cooling chamber 10110.

[0028] The exhaust fan 10104 is located on the top of the outer casing 10101 facing the paper inlet 10102, and an exhaust port 10105 is fixedly installed on the top of the exhaust fan 10104. The exhaust port 10105 facilitates connection to external pipes, making it convenient to recover and treat the steam or volatile organic compounds generated during the drying process of the device, thus avoiding pollution of the external environment.

[0029] The drying chamber 10111 is rotatably connected to five first guide rollers 10108. The five first guide rollers 10108 are arranged alternately at the bottom and top of the infrared heater 10107. The arrangement of the first guide rollers 10108 is such that two first guide rollers 10108 are located at the top of the infrared heater 10107 and three first guide rollers 10108 are located at the bottom of the infrared heater 10107. This facilitates the first guide rollers 10108 to form an "M" shape structure of the laser transfer paper inside the drying chamber 10111 and to wrap around the outside of the infrared heater 10107. This extends the path of the laser transfer paper inside the drying chamber 10111, allowing the device to fully dry the laser transfer paper.

[0030] The cooling chamber 10110 has two second guide rollers 10112 rotatably connected inside. The bottom end of the heat insulation plate 10109 has a channel. The second guide rollers 10112 facilitate the guidance of the dried laser transfer paper from the channel at the bottom end of the heat insulation plate 10109 into the cooling chamber 10110 for cooling.

[0031] The moving roller assembly 102 includes a driving roller 10201 and a driven roller 10202. Both the driving roller 10201 and the driven roller 10202 are disposed inside the housing 10101 and are rotatably connected to the housing 10101. The arrangement of the driving roller 10201 and the driven roller 10202 facilitates the rotation of the driving roller 10201 and the driven roller 10202 to drive the laser transfer paper into and out of the device.

[0032] Among them, a drive gear 10203 is fixedly installed at one end of the drive roller 10201, and a pulley 10205 is fixedly installed on one side of the drive gear 10203. Both the drive gear 10203 and the pulley 10205 are located on the outside of the housing 10101. Since both the drive gear 10203 and the pulley 10205 are located on the outside of the housing 10101, it is convenient for an external drive device to use a transmission belt sleeved on the outside of the pulley 10205 to drive the drive roller 10201 to rotate.

[0033] Among them, a driven gear 10204 is fixedly installed at one end of the driven roller 10202. The driven gear 10204 is located on the outside of the housing 10101 and is meshed with the driving gear 10203. The meshing connection between the driven gear 10204 and the driving gear 10203 facilitates the synchronous rotation of the driving roller 10201 and the driven roller 10202.

[0034] Specifically, the working principle of this drying device for laser transfer paper production is as follows: During use, both the drive gear 10203 and pulley 10205 are located on the outside of the outer casing 10101, facilitating the external drive device to use a transmission belt sleeved on the outside of the pulley 10205 to drive the drive roller 10201 to rotate. The driven gear 10204 meshes with the drive gear 10203, ensuring synchronous rotation of the drive roller 10201 and the driven roller 10202.

The infrared heater 10107 facilitates the heating and drying of the laser transfer paper inside the drying chamber 10111. The first guide rollers 10108 are positioned on top of the infrared heater 10107, with three... The first guide roller 10108 is located at the bottom of the infrared heater 10107, facilitating the formation of an "M"-shaped structure of the laser transfer paper inside the drying chamber 10111. It is also positioned around the outside of the infrared heater 10107, extending the path of the laser transfer paper within the drying chamber 10111 and ensuring thorough drying. An exhaust fan 10104 is fixedly installed at the top of the drying chamber 10111 to remove steam or volatile organic compounds generated during the drying process and to create a smooth flow inside the drying chamber. The negative pressure draws external airflow from the paper outlet 10103, through the cooling chamber 10110, and into the drying chamber 10111, thereby increasing the airflow speed inside the cooling chamber 10110 and cooling the dried laser transfer paper inside the cooling chamber 10110.
