Description

Technical Field

[0001] This utility model relates to the field of fan processing equipment, specifically a printing device. Background Technology

[0002] A fan includes both the fan ribs and the fan surface. The fan surface is mostly made of flexible materials. To improve the aesthetics of the fan surface, it is usually printed. Printing equipment is used to print the fan surface.

[0003] The printing equipment is a printing box, which contains a conveyor belt, a printing roller, and a pressing roller. The pressing roller and the printing roller are horizontally and linearly distributed, with the pressing roller located at the rear end of the printing roller. The conveyor belt is located at the lower end of both the printing roller and the pressing roller.

[0004] When using a printing box to print on a fan, the fan to be processed is placed on the conveyor belt. The conveyor belt moves and pushes the fan to the lower end of the printing roller and the lower end of the pressing roller. The printing roller runs to emboss the fan, while the pressing roller embosses the printed fan.

[0005] This type of printing box is simple to operate and easy to use, but its disadvantages are also obvious. For example, the positions of the printing roller and the embossing roller are fixed, and the gap between them is also fixed. When embossing fan surfaces of different thicknesses, it is necessary to adjust and replace the printing rollers of different thicknesses. Since the distance between the printing roller and the pressing roller is also relatively fixed, it is easy to have a hard collision with the pressing roller when replacing the printing roller, causing impact damage to the surface of the printing roller or the pressing roller, which will affect the printing quality of the fan surface in the future.

[0006] In view of the problems in the background art mentioned above, the present invention aims to provide a printing device. Utility Model Content

[0007] The purpose of this invention is to provide a printing device to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A printing apparatus, the printing apparatus comprising:

[0010] A printing box is provided to stably support the entire printing device. A slide frame is slidably mounted on the upper end of the printing box, and a printing roller is movably mounted on the slide frame. One end of the printing roller is connected to the output end of a servo motor, which is located on one side of the slide frame. The printing roller is used to perform printing operations on the soft material for making fans that is conveyed into the printing box.

[0011] A bracket is fixedly mounted on the carriage, and the printing roller is movably mounted on the bracket. A lifting component is also installed on the bracket to control the vertical height of the printing roller, thereby enabling the printing roller to achieve a good printing and embossing effect on soft materials of different thicknesses. In addition, a pushing component is installed on the printing box to push the carriage to slide at the upper end of the printing box, thereby adjusting the distance and gap between the printing roller and the pressure roller, and improving the printing quality of soft materials.

[0012] As a further embodiment of this utility model: the lifting assembly includes a hydraulic push rod, a traction rope, and an upper slider. The hydraulic push rod is located on the propulsion assembly, and the upper end of the hydraulic push rod is provided with a traction rope. The bracket includes a slide rod, and the upper slider is slidably mounted on the slide rod. At the same time, a rotating shaft is provided in the middle of the printing roller, and both ends of the rotating shaft are rotatably mounted on the upper slider. The upper slider is connected and fixed to the traction rope at the upper middle position. In addition, an upper pulley is movably mounted at the upper end of the bracket, and a lower pulley is movably mounted at the outer side of the slide. The traction rope runs along the outer surface of the upper pulley and the outer surface of the lower pulley to the upper end of the hydraulic push rod.

[0013] As a further embodiment of this utility model: the propulsion assembly includes a side slider, a side slide rail, and an electric push rod. The two sides of the side slide rail are fixed to the side of the printing box by fixing plates, and the side slider is slidably installed on the side slide rail. The upper end of the side slider is connected and fixed to the lower end of the slide frame by a connecting plate, and a hydraulic push rod is also installed on the upper end of the side slider. In addition, one side of the side slider is connected to the electric push rod, and the electric push rod is set on the printing box.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The printing device changes the original design where the positions of the printing rollers and pressure rollers installed inside the printing box were fixed. Through the cooperation of the lifting component and the pushing component, the height and lateral position of the printing rollers can be adjusted.

[0016] Therefore, there is no need to replace the printing roller when printing materials of different thicknesses; and after the printing roller has completed the printing operation on the fan surface, the distance between the printing roller and the pressure roller can be adjusted in time, which can not only avoid the pressure roller surface from hitting the printing roller surface and causing impact damage to the printing roller; but also improve the pressing quality of the subsequent pressing roller on the printed fan surface.

Detailed Implementation

[0021] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] Example

[0023] Please see Figure 1 and Figure 2 The present invention provides a printing device, the printing device comprising:

[0024] A printing box 1 is used to provide stable support for the entire printing device; wherein, a slide 7 is slidably installed on the upper end of the printing box 1, and a printing roller 11 is movably installed on the slide 7, one end of the printing roller 11 is connected to the output end of the servo motor 13; the printing roller 11 is used to perform printing operations on the soft material for making fans that is conveyed into the printing box 1.

[0025] A bracket 10 is fixedly mounted on the slide 7, and the printing roller 11 is movably mounted on the bracket 10. A lifting component is also mounted on the bracket 10. The lifting component is used to control the vertical height of the printing roller 11, so that the printing roller 11 can achieve a good printing and embossing effect on soft materials of different thicknesses. In addition, a pushing component is also mounted on the printing box 1. The pushing component is used to push the slide 7 to slide at the upper end of the printing box 1, thereby adjusting and changing the distance and gap between the printing roller 11 and the pressure roller, and improving the printing quality of soft materials.

[0026] In an embodiment of this utility model, when the printing device is used, the soft material to be processed is fed into the printing box 1 for conveying and displacement. The servo motor 13 is started, and the servo motor 13 drives the printing roller 11 to rotate, which is used to perform printing operations on the surface of the conveyed soft material. During the printing process of the printing roller 11, the vertical height position of the printing roller 11 can be adjusted by the set lifting component, so as to make it easier to produce a good printing effect on soft materials of different thicknesses. At the same time, the distance and gap between the printing roller 11 and the pressure roller can be adjusted by the installed pushing component, which is beneficial to improve the pressing quality of the pressure roller on the printed soft material.

[0027] In one embodiment of this utility model, the lifting assembly includes a hydraulic push rod 4, a traction rope 5, and an upper slider 8. The hydraulic push rod 4 is located on the propulsion assembly, and the traction rope 5 is provided at the upper end of the hydraulic push rod 4. The bracket 10 includes a slide rod 17, and the upper slider 8 is slidably mounted on the slide rod 17. At the same time, the printing roller 11 has a rotating shaft 12 in the middle, and the two ends of the rotating shaft 12 are rotatably mounted on the upper slider 8. The upper slider 8 is connected and fixed to the traction rope 5 at the upper middle position. In addition, an upper pulley 9 is movably mounted at the upper end of the bracket 10, and a lower pulley 6 is movably mounted at the outer side of the slide frame 7. The traction rope 5 reaches the upper end of the hydraulic push rod 4 along the outer surface of the upper pulley 9 and the outer surface of the lower pulley 6.

[0028] In the embodiments of this utility model, when the lifting assembly is activated to adjust the vertical height of the printing roller 11, for example, when it is necessary to raise the height of the printing roller 11 for printing on thicker soft materials, the hydraulic push rod 4 is activated, the hydraulic push rod 4 retracts, and the traction rope 5 is stretched. During the stretching process of the traction rope 5, the upper slider 8 will slide and displace on the slide rod 17, thereby raising the height of the printing roller 11. During the stretching process of the traction rope 5, the displaced traction rope 5 will be displaced along the surface of the upper pulley 9 and the surface of the lower pulley 6, which provides support for the stretched traction rope 5 and guides and positions the displaced traction rope 5.

[0029] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the propulsion assembly includes a side slider 3, a side slide rail 2, and an electric push rod 15. The side slide rail 2 is fixed to the side of the printing box 1 on both sides by fixing plates 14, and the side slider 3 is slidably mounted on the side slide rail 2. The upper end of the side slider 3 is connected and fixed to the lower end of the slide frame 7 by a connecting plate 16, and a hydraulic push rod 4 is also installed on the upper end of the side slider 3. In addition, one side of the side slider 3 is connected to the electric push rod 15, and the electric push rod 15 is set on the printing box 1.

[0030] In an embodiment of this utility model, for example, when the distance between the printing roller 11 and the pressure roller is adjusted by activating the propulsion assembly, the electric push rod 15 is activated. The electric push rod 15 drives the side slider 3 to slide on the upper surface of the side slide rail 2. Since the upper end of the side slider 3 is connected to the lower end of the slide frame 7 through the connecting plate 16, when the side slider 3 slides on the surface of the side slide rail 2, the slide frame 7 located at the upper end of the side slider 3 will slide along the upper surface of the printing box 1, thereby causing the printing roller 11 located at the upper end of the slide frame 7 to move closer to or separate from the distance between it and the pressure roller. By changing the distance between the printing roller 11 and the pressure roller, it is possible to avoid impact damage to the surface of the pressure roller when replacing the printing roller 11 because the original distance between the printing roller 11 and the pressure roller is too close. It is also possible to adjust the gap between the pressure roller and the printing roller later, thereby improving the pressing effect of the pressure roller on the printed soft material surface.

[0031] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] 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 and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
