Description

Technical Field

[0001] The utility model belongs to the technical field of packaging and printing, and particularly relates to a rapid drying device for the surface ink of a printed packaging color box. Background Art

[0002] A packaging carton is made of paper products and is used as a tool for packaging various items. Cartons are subdivided into paper boxes, color boxes, color cartons, and extra-large and oddly shaped beer boxes, etc. Among them, the packaging color box has the advantages of light weight, strong structure, moisture resistance, low transportation cost, convenient operation, environmental protection, etc. And because its surface is color-printed, the colors are bright and rich, can highlight the product brand, show the brand characteristics, and increase the publicity channels, etc., it is widely loved by manufacturers and consumers. After the packaging color box is printed, in order to avoid the pattern being blurred due to the scratching of the surface ink, a drying device is usually used to dry the ink to improve the production efficiency of the packaging color box. However, it still has the following disadvantages in actual use:

[0003] The utility model with the publication number of CN205149178U discloses a printing drying device. The air inlet pipe is communicated with the hot air pipe. A heater is arranged between the air inlet pipe and the hot air pipe. A fan is arranged between the heater and the air inlet pipe. One end of the hot air pipe extends into the lower part of the drying box and is fixedly connected with the drying box. An exhaust pipe is arranged at the top of the drying box. The exhaust pipe includes a return air pipe and an exhaust gas pipe. An activated carbon waste gas treatment machine is arranged on the exhaust gas pipe. The return air pipe is connected with the air inlet pipe. An adjustable air door is arranged on the return air pipe. The adjustable air door is connected with a motor. When the drying device dries printed matter, in order to avoid a large amount of heat loss with the air, a return air pipe is usually set to make the air circulate in the device. However, since the ink contains a certain amount of moisture, continuously circulating the hot air for a long time will inevitably cause the humidity of the hot air to increase continuously. If the humid hot air is not processed in time, it will affect the drying efficiency of the ink;

[0004] When the drying device dries the corrugated cardboard of the packaging color box, the printed corrugated cardboard may be bent at the end due to reasons such as roller printing. In order to avoid heat loss, the inlet and outlet of the drying device are usually close to the cardboard. When the cardboard is bent, the surface of the cardboard may contact the inlet, scratching the undried ink and affecting the finished product quality. Summary of the Utility Model

[0005] The purpose of the present utility model is to provide a rapid drying device for the surface ink of a printed packaging color box. By setting an L-shaped mounting frame, a heating support frame, and a filtering support frame, it solves the problems that when the drying device uses the hot air circulation method to dry the ink, the air humidity inside the device will increase with the increase of the drying time, affecting the ink drying efficiency, and the feeding and discharging ports of the drying device are relatively small. When the cardboard is bent, the feeding port may scrape the ink during the cardboard feeding, affecting the quality of the finished product.

[0006] To solve the above technical problems, the present utility model is realized through the following technical solutions:

[0007] The present utility model is a rapid drying device for the surface ink of a printed packaging color box, including an L-shaped mounting frame, a heating support frame, and a filtering support frame. A lifting cylinder is clamped at the top of the L-shaped mounting frame, a positioning suction cup is clamped and fixed on one side of the L-shaped mounting frame, a heating support frame is arranged on one side of the L-shaped mounting frame, a blower is penetrated and clamped at the inner top of the heating support frame, a filtering support frame is clamped and fixed at the top of the heating support frame, a heat preservation ventilation frame is penetrated and clamped at the top of the filtering support frame, and an infrared ranging component is clamped and fixed at the bottom of one side of the heat preservation ventilation frame;

[0008] The lifting cylinder can drive the up and down movement of the heating support frame to dry corrugated papers of different thicknesses. The positioning suction cup can quickly position the L-shaped mounting frame at one end of the production line. The operation is simple and convenient, and it is easy to maintain. The blower can drive the flow of hot air, so that the hot air blows to the surface of the corrugated cardboard for drying. The used hot air flows back into the filtering support frame through the heat preservation ventilation frame, and the filtering support frame filters moisture and dust to avoid the increase of humidity and ensure the drying efficiency. When the corrugated cardboard moves to the bottom of one side of the drying device through the conveyor belt, the infrared ranging component can monitor the height of the corrugated cardboard and control the lifting cylinder to drive the heating support frame to lift according to the thickness of the corrugated cardboard, avoiding the scraping of the ink caused by the bending of the corrugated cardboard and ensuring the quality of the finished packaging color box.

[0009] Further, a shock-absorbing plate is clamped and fixed on one side of the L-shaped mounting frame, and a limiting frame is welded and fixed at the top of the L-shaped mounting frame. The limiting frame, the lifting cylinder, and the shock-absorbing plate are all located on the side of the positioning suction cup of the L-shaped mounting frame;

[0010] The positioning suction cup can quickly fix the drying device at one end of the production line. The operation is simple and convenient, and it is easy to maintain. The shock-absorbing plate can reduce the influence of the vibration generated by the production line on the stability of the drying device.

[0011] Furthermore, a telescopic rod is slidably clamped at the top of the lifting cylinder, a connecting frame is clamped at the top of the telescopic rod, a reinforcing rib is welded and fixed to the top of the connecting frame, a limiting plate is welded and fixed to the bottom of the connecting frame, and the limiting plate is slidably clamped inside the top of the limiting frame;

[0012] The lifting cylinder can drive the telescopic rod to expand and contract, further driving the up and down movement of the connecting frame and the heating support frame, facilitating the drying treatment of corrugated cardboard with different thicknesses. The limiting frame can further ensure the stability of the heating support frame during lifting, and the reinforcing rib can improve the structural strength of the connecting frame, extending the service life of the drying device.

[0013] Furthermore, a heating plate is clamped and fixed to the inner bottom of the heating support frame. A plurality of ventilation holes are formed through the top of the heating plate. A temperature and humidity sensor is clamped and fixed inside the heating support frame. The temperature and humidity sensor is located between the blower and the heating plate. One side of the connecting frame and the reinforcing rib is welded and fixed to one end of the heating support frame;

[0014] The heating plate can heat the air. The ventilation holes can increase the heat conduction area of the heating plate, improving the heating speed of the air. The temperature and humidity sensor can monitor the temperature and humidity of the air passing through the heating support frame, avoiding the influence of excessive humidity on the drying efficiency.

[0015] Furthermore, an air extraction opening is formed through the bottom of the heat preservation and ventilation frame. The air extraction opening is located at the bottom of both sides of the heating support frame. A warning light is clamped and fixed to the top of the heat preservation and ventilation frame. Filter elements are inserted through both ends of the filter support frame;

[0016] The air extraction opening can make the hot air flow back, reducing heat loss. The filter elements can filter the moisture and dust in the air, avoiding the influence on drying. And after heating for a certain time, when the humidity is monitored to rise, the warning light lights up to remind the staff. The staff can quickly insert another filter element into the filter support frame, and the operation is simple and convenient.

[0017] The utility model has the following beneficial effects:

[0018] The utility model solves the problem that when a drying device dries printed matter, in order to avoid a large amount of heat loss with air, a return air duct is usually set to make the air circulate in the device. However, since the ink contains a certain amount of moisture, continuously circulating hot air for a long time will inevitably lead to an increasing humidity of the hot air. If the humid hot air is not processed in time, it will affect the drying efficiency of the ink. The blower drives the flow of hot air to dry the corrugated cardboard. The dried air flows back through the heat preservation ventilation frame and is dehumidified and purified through the filter element. The humidity of the air entering the heating support frame is monitored by a temperature and humidity sensor to ensure that the hot air for drying the corrugated cardboard is always relatively dry. When the filter element fails, a warning light is used to prompt the staff and the filter element is replaced in time to avoid the humid hot air reducing the drying efficiency of the corrugated cardboard.

[0019] The utility model solves the problem that when a drying device dries the corrugated cardboard of a packaging color box, due to reasons such as roller printing, the end of the printed corrugated cardboard may be bent. In order to avoid heat loss, the inlet and outlet of the drying device are usually close to the cardboard. When the cardboard is bent, the surface of the cardboard may contact the inlet, causing scratching to the undried ink and affecting the quality of the finished product. When the corrugated cardboard moves to the bottom on one side of the drying device through the conveyor belt, the infrared ranging component can monitor the height of the corrugated cardboard and control the lifting cylinder to drive the heating support frame to lift according to the thickness of the corrugated cardboard, avoiding scratching of the ink caused by the bending of the corrugated cardboard and ensuring the quality of the finished packaging color box.
