Description

Technical Field

[0001] This utility model relates to the field of printing technology, and in particular to a constant temperature drying device for printing. Background Technology

[0002] Printing is a technology that involves transferring ink from original manuscripts such as text, pictures, photographs, and anti-counterfeiting materials to the surface of materials like paper, textiles, plastics, leather, PVC, and PC through processes such as plate making, inking, and pressing. Drying the printed materials is a crucial step affecting both quality and efficiency.

[0003] However, existing constant temperature drying equipment has the following problems:

[0004] Traditional temperature control mechanisms often use a single heating method, such as a simple electric heating tube, which leads to uneven temperature distribution in the drying chamber, low heat conduction efficiency, and high energy consumption, making it difficult to meet the precise temperature control requirements of printed materials of different materials. The transport mechanism relies on unidirectional power roller transmission and lacks efficient lateral adjustment function. Printed materials are prone to displacement or wrinkling due to tension changes, which affects the drying effect or leads to uneven drying distribution and inconsistent drying effects in different parts.

[0005] To address the aforementioned shortcomings, there is an urgent need for a constant temperature drying device for printing that offers uniform temperature control, stable transmission, and high adjustability. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0027] See Figures 1-6 This utility model provides a constant temperature drying device for printing, including a transport mechanism 1 and a temperature control mechanism 2, which work together to achieve stable transport and constant temperature drying of printed materials.

[0028] The transport mechanism 1 includes a transport platform 101, which is a rectangular frame structure. The upper surface is covered with a smooth transmission plate for carrying printed materials. Several power rollers are intermittently arranged on the transmission plate. The power rollers are evenly arranged along the length of the transport platform 101, with intervals of 20cm to 50cm, and a total of 5 to 10 rollers are set. Both ends are fixed to the side frames of the transport platform 101 by bearing seats.

[0029] The power motor is a servo motor, installed at one end of the transport platform 101, and connected to the first power roller through a synchronous belt or gear set, driving all power rollers to rotate in the same direction.

[0030] It also includes a lateral adjustment mechanism, including an adjustment groove 401, which is located in the middle of the transport platform 101, corresponding to the temperature control chamber 201 area. The adjustment groove 401 is a rectangular groove.

[0031] The adjusting rollers 402 are arranged in a cross-transport direction, with a cross angle of -60° to 60° from the transport direction. A total of 4 to 6 groups are set, and each group contains 2 adjusting rollers 402 symmetrically distributed on both sides of the adjusting groove 401. The adjusting rollers 402 on both sides rotate in opposite directions.

[0032] Each adjusting roller 402 is fixed on both sides of the adjusting groove 401 by a rotating shaft, and the outer end of the rotating shaft is connected to the drive shaft 404.

[0033] The drive motor 405 is installed on the side of the transport table 101 and is connected to the main drive shaft 404 through a reducer. The main drive shaft 404 is connected to the drive shaft 404 on the same side through a drive belt 406. The drive shafts 404 on different sides are engaged by drive gears 407 to realize the adjustment roller 402 to move the printed matter laterally.

[0034] The temperature control mechanism 2 includes a temperature control chamber 201, which is rectangular and divided into an inner chamber 202 and an outer chamber 203. The inner chamber 202 is made of high-temperature resistant stainless steel, and the outer chamber 203 is made of insulation material. The two are spaced 5-10cm apart to form a sandwich.

[0035] The transmission holes are evenly distributed on both sides of the inner chamber 202 to conduct heat from the outer chamber 203 to the inner chamber 202.

[0036] The temperature control unit 205 includes a heating tube installed in the interlayer of the outer chamber 203 and arranged along the length of the inner chamber 202. It can use a combination of electric heating tubes for rapid heating, water heating tubes for constant temperature control, and steam heating tubes for wet drying. The steam heating tube is equipped with an exhaust fan to absorb water vapor. The heating mode is switched by a temperature control switch.

[0037] A temperature sensor is installed on the top of the temperature control chamber 201 to provide real-time feedback on the temperature inside the drying chamber 204. The power of the heating tube is adjusted through the PLC control system to achieve constant temperature control of 20-150℃.

[0038] It also includes a lifting mechanism 3, which includes telescopic rods, which are electric push rods or hydraulic telescopic rods, symmetrically installed at the four corners of the bottom of the transport table 101. The height of the transport table 101 is adjusted by the controller to adapt to different drying chamber 204 height requirements or changes in the thickness of printed materials.

[0039] The working process of this utility model:

[0040] This utility model relates to a constant temperature drying device for printing. When in use, the printed matter is placed at the front end of the transport table 101, the power motor is started, and the power roller drives the printed matter into the temperature control chamber 201 at a uniform speed along the transport direction.

[0041] When the printed material enters the adjustment tank 401 area, the drive motor 405 starts, and the adjustment roller 402 pushes the printed material to move laterally by rotating in the opposite direction, correcting the offset and aligning the center position to prevent the edges from contacting the tank wall during drying.

[0042] Based on the material and process requirements of the printed matter, the heating tube combination is selected through the control system, and the target temperature is set.

[0043] The heat generated by the heating tube in the outer chamber 203 is evenly conducted to the drying chamber 204 in the inner chamber 202 through the transmission hole. The temperature sensor provides real-time feedback and adjusts the heating power to ensure that the temperature inside the drying chamber 204 is stable.

[0044] If the printed material is thick, the height of the transport table 101 can be lowered by the lifting mechanism 3 to adjust the distance between it and the heating tube, thereby improving the drying efficiency.

[0045] After the printed matter is completely dried in the drying chamber 204, it is sent out of the temperature control chamber 201 by the power roller and collected at the rear unloading station.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
