Description

Technical Field

[0001] The utility model relates to an air circulation device for a printing press. Background Art

[0002] During the printing process, in order to avoid dust from getting on the printed materials, the dust in the air needs to be removed. However, printing machines are generally equipped with ovens. Both ovens and air purification equipment require fans. A large number of fans will increase the noise in the printing workshop. At the same time, due to the different air inlet areas of the oven and the air purification equipment, dusty air will be inhaled into the oven. If it is discharged in the workshop, the amount of dust in the operating workshop will increase. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings, the utility model provides an air circulation device for a printing press, which reduces the number of fans and effectively controls the amount of dust in a workshop.

[0004] To achieve this purpose, the structure adopted by the utility model is: a printing press air circulation device, including a base, a transition box and an oven, a plurality of transition boxes are symmetrically arranged on both sides of the bottom of the oven, the bottom of the transition box is connected to the base, an air inlet is arranged on the base, a fan is arranged on the transition box, the fan draws air in from the air inlet and sends it into the oven, a filter is arranged in the transition box, and an air heater is arranged at the air inlet of the oven.

[0005] A plurality of filter screens are arranged from bottom to top in the transition box, the filter screens are connected to the plug board of the rectangular frame structure, a slot is arranged on the side of the transition box, and the filter screens are inserted into the transition box from the slot.

[0006] The air inlet is arranged on the side of the base.

[0007] A movable partition is arranged inside the base, the top of the movable partition is connected to the base through a rotating shaft, the end of the rotating shaft is connected to a handle, and the handle is arranged outside the base.

[0008] The beneficial effects are: the structural design of the utility model is reasonable and ingenious. After the fan is turned on, the surrounding dusty air enters from the air inlet, is filtered by the heavy filter screen of the transition box, and is then sent into the drying oven after being heated by the air heater. On the one hand, the number of fans is reduced, and the noise entering the workshop is reduced. At the same time, no air with dust from the outside will enter, and the amount of dust in the air in the workshop can be controlled. At the same time, the hot air in the oven is evenly distributed, which improves the drying efficiency and drying quality. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0013] In the description of the utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components; the fixed connection can be welding or gluing. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0014] like Figure 1 The printing press air circulation device shown includes a base 1, a transition box 3 and an oven 5. A plurality of transition boxes 3 are symmetrically arranged on both sides of the bottom of the oven 5. Adjacent transition boxes 3 are spaced 3-8 m apart. The bottom of the transition box 3 is connected to the base 1. An air inlet 2 is provided on the base 1. A fan 6 is provided on the transition box 3. One fan 6 is connected to one or more transition boxes 3. The fan 6 draws air in from the air inlet 2 and sends it into the oven 5. A filter 4 is provided in the transition box 3. An air heater 7 is provided at the air inlet of the oven 5.

[0015] A plurality of filters 4 are arranged from bottom to top in the transition box 3, and the filters 4 are connected to a plug-in board of a rectangular frame structure. A slot is arranged on the side of the transition box 3, and the plug-in board connected with the filters 4 is inserted into the transition box 3 from the slot. The plug-in board is a metal frame, and the edge of the metal frame contacts the transition box 3. The metal frame extends to the outside of the transition box 3, and a sealing strip is arranged on the part of the outside of the metal frame contacting the transition box 3.

[0016] The air inlet 2 is arranged on the front and rear sides of the base 1. The height of each base 1 is 15 to 25 cm. The air inlet 2 faces the feeding direction of the material on the printing machine. A grille is arranged at the air inlet 2. The grille includes multiple L-shaped strips arranged on a rectangular frame, so that airflow enters from the left and right sides of the base 1.

[0017] A movable partition is arranged inside the base 1, and the top of the movable partition is connected to the base 1 through a rotating shaft. The end of the rotating shaft is connected to a handle, and the handle is arranged outside the base. A lock is arranged between the rotating shaft and the base 1 to fix the rotation angle of the movable partition. When the movable partition is kept vertical, the base 1 is divided into two left and right boxes.

[0018] The utility model has a reasonable and ingenious structural design. The fan 6 draws the dusty air in the workshop from the air inlet 2, and the airflow passes through the filter in the transition box 3 to filter out the dust layer by layer. When there is too much dust on the filter 4, the plug plate is pulled out from the slot for cleaning and then inserted to avoid the reduction of the airflow due to the blockage of the filter 4. The filtered air is heated by the air heater 7 and then sent to the oven 5. Since the transition boxes 3 are evenly distributed on both sides of the oven 5, the uniform distribution of the hot air in the oven 5 can be guaranteed. At the same time, the air temperature in the oven 5 at different stages can be adjusted as needed to improve the flexibility of the oven. The air discharged from the oven 5 is still clean, and the amount of dust in the workshop will not be increased when it is discharged into the workshop, thereby ensuring the cleanliness of the workshop air.

[0019] The above is based on the enlightenment of this utility model. Through the above description, relevant staff can make various changes and modifications without deviating from the technical idea of ​​this utility model. The technical scope of this utility model is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
