Description

Technical Field

[0001] This utility model relates to the field of ice point snowflake printing technology, and in particular to a drying device for an ice point snowflake printing machine. Background Technology

[0002] With the rapid development of printing technology and the continuous improvement of consumers' aesthetic standards, the quality requirements for various promotional printed materials and packaging products are becoming increasingly stringent. In particular, decorative inks that can produce a snow-like or ice-crystal effect on the surface of printed materials (commonly known in the industry as "snowflakes" and "ice points," respectively, depending on the size of the pattern) are widely used in high-end printed materials such as cigarette and alcohol boxes, calendars, and gift boxes because of their full ink film, wear resistance, strong adhesion, long-lasting color, and delicate touch. At the same time, they present delicate patterns, a strong three-dimensional effect, and a luxurious and elegant temperament.

[0003] However, during the printing process, these exquisite ink patterns need to be dried and cooled to be fixed. In order to ensure that the printed material will not be oxidized by oxygen, the drying chamber needs to be continuously filled with oxygen-free protective gas. However, in actual operation, since the printing equipment is not completely sealed, a small amount of oxygen will inevitably seep into the drying chamber and mix with the protective gas, thereby interfering with the normal progress of the drying process and even causing problems with the quality of the finished product. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution: a drying device for an ice-point snowflake printing machine, comprising a base, an inlet on one side of the base, a conveyor belt for conveying the material to be dried installed below the inlet, a gas chamber installed above the base, a storage chamber fixedly installed on the other side of the base, a drying chamber inside the base, a sensor controller installed inside the drying chamber, multiple sets of ultraviolet lamps installed above the inside of the drying chamber, several fixed plates installed above the inside of the base, connecting pipes communicating with the gas chamber opened above the fixed plates, several conveyor heads installed below the fixed plates, and a recycling component arranged on the inner side of the drying chamber above the conveyor belt.

[0005] As an improvement to the above technical solution, the recycling component includes a recycling head, and there are several recycling heads, all of which are installed on the inner side of the drying chamber and above the conveyor belt. The side of the recycling head has a recycling pipe inside the outer wall of the base, and a connecting pipe is opened inside the upper outer wall of the base. The connecting pipe connects the several recycling pipes and is connected to the storage chamber.

[0006] As an improvement to the above technical solution, the ultraviolet lamp tube is installed in a U-shape inside the drying chamber.

[0007] As an improvement to the above technical solution, the fixing plate is installed between each ultraviolet lamp tube.

[0008] As an improvement to the above technical solution, a movable groove is provided on the base on one side of the drying chamber, and several limiting grooves are provided on one side of the movable groove. An air knife is movably installed inside the movable groove. A card slot is provided on the side of the movable groove adjacent to the limiting groove. A card plate is detachably installed inside the limiting groove and the card slot.

[0009] The beneficial effects of this utility model are as follows: The drying chamber inside the base provides a drying environment for the material to be dried. The application of a sensor controller enables precise monitoring of the concentration of the protective gas inside the drying process, ensuring the accuracy and stability of the drying temperature. The installation of multiple sets of ultraviolet lamps not only provides an efficient drying heat source, but the setting of the fixing plate and conveyor head also allows the gas to be delivered evenly and efficiently into the drying chamber, accelerating the drying speed of the material. Simultaneously, the connection between the connecting pipe and the gas chamber ensures a continuous gas supply. The recovery component installed on the inner side of the drying chamber effectively recovers and reuses the underutilized protective gas during the drying process, ensuring that the concentration of the internal protective gas is always maintained within the specified range, while avoiding environmental pollution and resource waste, and reducing resource consumption.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0017] Please see Figure 1-5 This utility model provides a technical solution: a drying device for an ice point snowflake printing machine, including a base 10, a feed inlet 12 on one side of the base 10, a conveyor belt 11 for conveying the material to be dried installed below the feed inlet 12, a gas chamber 13 installed above the base 10, a storage chamber 14 fixedly installed on the other side of the base 10, a drying chamber 20 inside the base 10, a sensor controller 15 installed inside the drying chamber 20, multiple sets of ultraviolet lamps 21 installed above the inside of the drying chamber 20, several fixed plates 22 installed above the inside of the base 10, a connecting pipe 23 communicating with the gas chamber 13 opened above the fixed plates 22, several conveyor heads 24 installed below the fixed plates 22, and a recycling component is provided on the inner side of the drying chamber 20 above the conveyor belt 11.

[0018] In this embodiment, the drying chamber 20 inside the base 10 provides a drying environment for the material to be dried. The application of the sensor controller 15 enables precise monitoring of the concentration of the protective gas inside the drying process, ensuring the accuracy and stability of the drying temperature. The installation of multiple sets of ultraviolet lamps 21 not only provides an efficient drying heat source, but also, with the setting of the fixing plate 22 and the conveying head 24, the gas can be uniformly and efficiently delivered into the drying chamber 20, accelerating the drying speed of the material. At the same time, the connection between the connecting pipe 23 and the gas chamber 13 ensures a continuous supply of gas. The recovery component set on the inner side of the drying chamber 20 can effectively recover and reuse the protective gas that was not fully utilized during the drying process, ensuring that the concentration of the internal protective gas is always maintained within the specified range, while avoiding environmental pollution and resource waste, and reducing resource consumption.

[0019] Specifically, the recycling component includes a recycling head 25, and there are several recycling heads 25, all of which are installed inside the drying chamber 20 and above the conveyor belt 11. The recycling head 25 has a recycling pipe 26 inside the outer wall of the base 10 on its side. A connecting pipe 27 is opened inside the outer wall above the base 10. The connecting pipe 27 connects several recycling pipes 26 and is connected to the storage chamber 14.

[0020] In this embodiment, the introduction of the recycling component further enhances the practicality and environmental performance of the drying device for the ice-point snowflake printing machine. Specifically, by setting multiple recycling heads 25 on the inner side of the drying chamber 20, it is possible to ensure that when the sensor controller 15 detects that the concentration of protective gas inside the drying chamber 20 is insufficient, the recycling component is activated to promptly recover the insufficient protective gas, ensuring that the concentration of protective gas inside the drying chamber 20 is always maintained at a suitable concentration, ensuring the drying effect, and preventing oxidation reactions during printing. The recycling heads 25 and recycling pipes 26 ensure that the substandard protective gas is smoothly introduced into the recycling pipes 26 inside the outer wall of the base 10. The design of the connecting pipe 27 effectively connects multiple recycling pipes 26, forming a complete recycling network, which allows it to flow to the storage chamber 14 in a centralized and orderly manner. The storage chamber 14 is equipped with a filter and purifier to separate and filter the recovered gas into other gases and protective gas. The protective gas is reserved for the next use, avoiding waste of resources and environmental pollution, saving costs for enterprises, and improving resource utilization efficiency.

[0021] Specifically, the ultraviolet lamp 21 is installed in a U-shape inside the upper part of the drying chamber 20.

[0022] In this embodiment, the U-shaped design of the ultraviolet lamp 21 installed inside the upper part of the drying chamber 20 optimizes the performance of the drying device, ensuring that ultraviolet rays can more comprehensively irradiate the material to be dried, thus improving drying efficiency. The U-shaped lamp design allows the light to cover a wider area, reducing blind spots and ensuring the uniformity of material drying. Uneven drying may lead to problems such as material deformation, cracking, or uneven color. In addition, the U-shaped lamp is easy to install and maintain. Due to its compact structure, it occupies relatively little space, which makes the internal design of the drying chamber 20 more reasonable and also reduces production costs.

[0023] Specifically, the fixing plate 22 is installed between each ultraviolet lamp tube 21.

[0024] In this embodiment, firstly, the fixed plate 22 provides a stable support structure for the gas conveying system, ensuring that the gas can flow smoothly and evenly through the connecting pipe 23 to the conveying head 24, and then be evenly distributed on the material to be dried. This helps to speed up the drying process and improve the drying efficiency. At the same time, it can fill the entire drying chamber 20, so that the entire drying chamber 20 can be quickly filled when the protective gas is released.

[0025] Specifically, a movable groove 31 is provided on the base 10 on one side of the drying chamber 20. Several limiting grooves 30 are provided on one side of the movable groove 31. An air knife 32 is movably installed inside the movable groove 31. A slot 33 is provided on the side of the movable groove 31 adjacent to the limiting groove 30. A card plate 34 is detachably installed inside the limiting groove 30 and the slot 33.

[0026] In this embodiment, the air knife 32 can move flexibly within the drying chamber 20 via the moving groove 31. The user can precisely adjust the position of the air knife 32 according to the thickness of the material to achieve the best effect. The design of the limiting groove 30 and the slot 33, as well as the detachable clamping plate 34, provides stable support and positioning for the air knife 32. The user can easily install the clamping plate 34 in the limiting groove 30 and the slot 33 as needed, thereby fixing the position of the air knife 32. This detachable design not only facilitates the quick installation and removal of the air knife 32, but also allows the user to make fine adjustments to the position as needed, further improving the accuracy and controllability of the drying process.

[0027] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
