Description

Technical Field

[0001] The utility model relates to the technical field of printing machines, in particular to an arc oven used in a digital printing machine. Background Art

[0002] When the digital printing machine prints, the cloth on the rotating cloth-threading roller is printed through the printing nozzle. After printing is completed, the printed cloth-threading roller rotates to the dryer station for drying. The drying method is that a heating device is fixedly provided on one side of the cloth-threading roller, and the cloth-threading roller that needs to be dried is moved above the heating device and dried by the heating device.

[0003] The above-mentioned existing drying method has the following defects: since the cloth-threading roller itself is cylindrical, it needs to rotate multiple times during the drying process so that the cloth at different parts of the cloth-threading roller is dried in turn by the heating device below. This method results in low drying efficiency, long drying cycle, and large heat loss of the heating device. Utility Model Content

[0004] In view of the defects existing in the prior art, the purpose of the utility model is to provide an arc oven for a digital printing machine to solve the problems of low drying efficiency of existing printed fabrics and large heat loss of the heating device.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] Furthermore, a lower driving cylinder is provided on the outer side of the lower oven heating device, and the lower oven heating device forms a vertical sliding connection with the bracket. The lower driving cylinder is fixedly installed at the bottom end of the bracket, and the piston rod of the lower driving cylinder is connected to the lower oven heating device for driving the lower oven heating device to move up and down.

[0008] Furthermore, an upper driving cylinder is provided on the outer side of the upper oven heating device, and the upper oven heating device forms a vertical sliding connection with the bracket. The upper driving cylinder is fixedly installed at the top of the bracket, and the piston rod of the upper driving cylinder is connected to the upper oven heating device for driving the upper oven heating device to move up and down.

[0009] Furthermore, the upper oven heating device and the lower oven heating device are provided with arc-shaped heating reflecting surfaces.

[0010] Furthermore, adjustment pads are respectively arranged around the bottom end of the bracket.

[0011] The beneficial effects of the utility model are as follows: an upper oven heating device and a lower oven heating device are arranged opposite to each other, and an accommodation space is reserved between the two for the cloth threading roller to enter horizontally; this structural method can make the printed cloth on the cloth threading roller be baked up and down at the same time, with high heating efficiency, and the method of heating up and down at the same time reduces the heat loss of the oven heating device, and can better concentrate the heat to heat the printed cloth in the middle position.

[0017] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0018] See attached Figure 1 To Attachment Figure 3 As shown, this embodiment provides an arc oven 100 for a digital printing machine, which includes a bracket 1, a lower oven heating device 2 and an upper oven heating device 3, the lower oven heating device 2 is installed at the bottom end of the bracket 1, the upper oven heating device 3 is installed at the top end of the bracket 1, the upper oven heating device 3 and the lower oven heating device 2 are opposite to each other in vertical direction, and an accommodating space 7 for horizontal entry of a cloth threading roller 200 is formed between the upper oven heating device 3 and the lower oven heating device 2.

[0019] In order to adjust the installation position of the upper oven heating device 3 and / or the lower oven heating device 2 to change the upper and lower distances of the accommodating space 7, the outer surface of the lower oven heating device 2 forms a vertical sliding connection with the bracket 1, and the lower oven heating device 2 is provided with a lower driving cylinder 4. The lower driving cylinder 4 is fixedly mounted at the bottom end of the bracket 1, and the piston rod of the lower driving cylinder 4 is fixedly connected to the lower oven heating device 2. When the installation position of the lower oven heating device 2 needs to be adjusted, the piston rod of the lower driving cylinder 4 is pushed upward, driving the lower oven heating device 2 to move up and down along the bracket 1.

[0020] Similarly, the outer surface of the upper oven heating device 3 forms a sliding connection with the bracket 1 in the vertical direction, and the upper oven heating device 3 is externally connected with an upper driving cylinder 5. The upper driving cylinder 5 is fixedly installed on the top of the bracket 1, and the piston rod of the upper driving cylinder 5 is fixedly connected to the upper oven heating device 3. When the installation of the upper oven heating device 3 needs to be adjusted, the piston rod of the upper driving cylinder 5 is pushed downward to drive the upper oven heating device 3 to move up and down along the bracket 1. It can be understood that when the distance between the upper oven heating device 3 and the lower oven heating device 2 needs to be adjusted, it can be flexibly adjusted by driving the upper driving cylinder 5 or the lower driving cylinder 4.

[0021] Continue to refer to the attached Figure 2 and attached Figure 3 As shown, in order to improve the heating effect, an arc-shaped reflecting surface 6 is installed in the upper heating device and the lower heating device, so that part of the heat generated by the upper heating device and the lower heating device can be reflected to the printed fabric on the cloth threading roller 200 by means of the arc-shaped reflecting surface 6 to heat the printed fabric.

[0022] When the printed fabric is dried, the upper oven heating device 3 and / or the lower oven heating device 2 can be lowered and raised respectively, so as to form enough space so that the cloth-threading roller 200 can rotate horizontally and enter the accommodating space 7. After the cloth-threading roller 200 moves to the correct position, the oven heating device 3 and the lower oven heating device 2 are moved to the vicinity of the upper end surface and the lower end surface of the cloth-threading roller 200, and the printed fabric on the cloth-threading roller 200 is dried and heated. For example, when the cloth-threading roller 200 rotates and enters, the lower oven heating device 2 automatically lowers downward to allow the cloth-threading roller 200 to have enough space to enter; when the cloth-threading roller 200 reaches the correct position, the lower oven heating device 2 automatically rises to be as close to the cloth-threading roller 200 as possible, so as to reduce heat loss, improve baking effect, and save energy and reduce consumption. Or for example, when the cloth-threading roller 200 rotates and enters, the upper oven heating device 3 automatically rises to allow the cloth-threading roller 200 to have enough space to enter. When the cloth-threading roller 200 reaches the correct position, the upper oven heating device 3 automatically descends to be close to the cloth-threading roller 200 feeding, thereby reducing heat loss, improving the baking effect, and saving energy and reducing consumption. It is understandable that the above two working modes can be flexibly selected as needed. During the heating process, the cloth-threading roller 200 can be rotated according to the set heating time to ensure the drying effect of the printed fabric. After the printed fabric on the cloth-threading roller 200 is heated and dried, the upper oven heating device 3 and the lower oven heating device 2 move away from each other, and the cloth-threading roller 200 slides out horizontally from the accommodating space 7, and the next printed fabric that has been printed enters the accommodating space 7 for drying, and the above process is repeated.

[0023] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include these modifications and variations.
