[0002] Non-woven bags are a type of green and environmentally friendly packaging bag that has been widely used in daily life and business in recent years. Non-woven bags are made of polypropylene, a non-toxic and odorless thermoplastic synthetic resin. Non-woven bags are soft and comfortable to the touch and will not scratch or damage the packaged items.

[0003] The drying device for gravure printing machines used in non-woven bag processing plays a crucial role in the production process. After the non-woven bags are printed by the gravure printing machine, they enter the drying device. The drying temperature is then monitored and adjusted in real time by a temperature control system to ensure that the ink dries at a suitable temperature.

[0004] The existing drying equipment for gravure printing machines used in non-woven bag processing relies on a hot air system for drying. This drying method mainly uses wind energy to blow heat onto the non-woven bags for drying. During the drying process, problems such as uneven drying and hot air deforming the printing ink may occur. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a drying device for a gravure printing machine for non-woven bag processing, which aims to improve the uneven drying during hot air drying in the prior art and the problem of hot air deforming the ink.

A pressing rod is fixedly connected to the lower front end of the delay gear rod. A transmission switch is fixedly connected to the upper front side of the inner wall of the support frame. A second conveyor belt is rotatably connected to the lower left side of the support frame.

[0009] As a further description of the above technical solution:

[0010] Limiting strips are installed on the front and rear sides of the outer wall of the conveyor belt, and multiple thumbtacks are fixedly connected at equal intervals to the outer walls of the two limiting strips.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 and Figure 3This utility model provides an embodiment of a drying device for a gravure printing machine used for processing non-woven bags, including a support frame 1. A motor 3 is fixedly connected to the right side of the inner top wall of the support frame 1. A drive sprocket 4 is fixedly connected to the output end of the motor 3, and the motor 3 drives the drive sprocket 4 to rotate. A rotating rod 7 is rotatably connected to the middle right side of the support frame 1. A driven sprocket 5 is fixedly connected to the front end of the rotating rod 7. The drive sprocket 4 is connected to the driven sprocket 5 through a chain 6. The drive sprocket 4 achieves the rotation of the rotating rod 7 through the chain 6 and the driven sprocket 5. A high-temperature barrel 8 is fixedly connected to the outer wall of the rotating rod 7, and the rotating rod 7 drives the high-temperature barrel 8 to rotate. A transmission and packaging mechanism 2 is installed in the middle of the support frame 1. The transmission and packaging mechanism 2 is used for the transmission of non-woven bags. A fixing rod 15 is fixedly connected to the upper right side of the support frame 1. A heat-concentrating cover 16 is fixedly connected to the outer wall of the fixing rod 15. The heat-concentrating cover 16 concentrates the heat energy generated by the high-temperature barrel 8 downward.

[0033] Specifically, when the drying device of the gravure printing machine for non-woven bag processing starts operating, the motor 3 provides power to drive the drive sprocket 4 to rotate. When the drive sprocket 4 rotates, it drives the driven sprocket 5 fixed on the rotating rod 7 to rotate synchronously through the chain 6. When the driven sprocket 5 rotates, it drives the rotating rod 7 to rotate together. When the rotating rod 7 rotates, the high-temperature barrel 8 fixed on it will also rotate synchronously. The rotation speed of the high-temperature barrel 8 is synchronized with the transmission speed of the non-woven bag, thereby achieving the effect of uniform drying of the non-woven bag and preventing the printing ink from being blown and deformed. The heat-concentrating cover 16 fixed by the fixing rod 15 can prevent the heat energy generated by the high-temperature barrel 8 from dissipating to the surroundings and can concentrate the heat energy downwards.

[0034] Reference Figure 4 and Figure 5 The transmission and subcontracting mechanism 2 includes a conveyor belt 201, which is rotatably connected to the lower right side of the support frame 1. Multiple teeth 202 are fixedly connected at equal intervals on the front side of the conveyor belt 201. A delay gear rod 203 is fixedly connected to the middle of the front side of the inner wall of the support frame 1. The delay gear rod 203 meshes with the teeth 202. The conveyor belt 201 drives the delay gear rod 203 to rotate through the teeth 202. A pressing rod 204 is fixedly connected to the lower front end of the delay gear rod 203. A transmission switch 20 is fixedly connected to the upper middle of the front side of the inner wall of the support frame 1. 5. A second conveyor belt 206 is rotatably connected to the lower left side of the support frame 1. When the delay gear rod 203 rotates, the operation of the second conveyor belt 206 is controlled by the pressing rod 204 and the transmission switch 205. Limiting strips 9 are installed on the front and rear sides of the outer wall of the first conveyor belt 201. Multiple thumbtacks 10 are fixedly connected at equal intervals on the outer walls of the two limiting strips 9. The limiting strips 9 can prevent the non-woven bags from shifting during transmission. A dust cover 11 is installed in the upper middle part of the support frame 1. A screw 12 is threadedly connected to the upper middle part of the dust cover 11. The dust cover 11 can prevent dust from falling into the transmission switch 205.

[0035] Specifically, when the drying device of the gravure printing machine for non-woven bag processing starts operating, the non-woven bags are first dried through the drying system of conveyor belt 201. After drying, they continue to be conveyed forward. The dried non-woven bags are transferred from conveyor belt 201 to conveyor belt 206. During this process, multiple teeth 202 fixed beside conveyor belt 201 will sequentially mesh with the delay gear rod 203, thereby driving the rotation of the delay gear rod 203. When the delay gear rod 203 rotates once, the pressing rod 204 fixed on it will press the upper part once. The transmission switch 205 has a transmission button, and the spacing of the teeth 202 corresponds exactly to the spacing of the non-woven bags on the first conveyor belt 201. Each time the transmission switch 205 is pressed, the second conveyor belt 206 will move forward a certain distance, thus achieving the effect of transmitting and packaging non-woven bags. The limit strips 9 fixed on both sides of the first conveyor belt 201 by the thumbtack 10 can prevent the non-woven bags from shifting during transmission. The dust cover 11 fixed by the screw 12 can provide dust protection for the transmission switch 205. The motor 3 is model YR-315M.

[0036] Reference Figure 1 and Figure 2 A top rail 13 is installed on the top left side of the support frame 1. Screws 14 are threaded at equal intervals on the left and right sides of the top rail 13. The top rail 13 can provide protection for the equipment. Fixing rods 17 are fixedly connected at equal intervals on the upper left side of the support frame 1. Guide plates 18 are fixedly connected to the bottom of the two fixing rods 17. The guide plates 18 guide the non-woven bags to fall neatly from the conveyor belt 201 onto the conveyor belt 206. An X-shaped frame 19 is installed on the rear side of the support frame 1. Screws 20 are threaded at the four corners of the X-shaped frame 19. The X-shaped frame 19 can make the support frame 1 more stable.

[0037] Specifically, the top rail 13, fixed by screw 2 14, can provide effective protection for the conveying and packaging mechanism 2; the guide plate 18, fixed by fixing rod 2 17, can ensure that the non-woven bags are neatly conveyed from conveyor belt 1 201 to conveyor belt 2 206; and the X-shaped frame 19, fixed to the rear side of the equipment support frame 1 by screw 3 20, can make the support frame 1 more stable.

[0038] Working principle: When the drying device of the gravure printing machine for non-woven bag processing starts to operate, the motor 3 provides power to drive the drive sprocket 4 to rotate. When the drive sprocket 4 rotates, it drives the driven sprocket 5 fixed on the rotating rod 7 to rotate synchronously through the chain 6. When the driven sprocket 5 rotates, it drives the rotating rod 7 to rotate together. When the rotating rod 7 rotates, the high temperature barrel 8 fixed on it will also rotate synchronously. The rotation speed of the high temperature barrel 8 is synchronized with the transmission speed of the non-woven bag, thereby achieving the effect of uniform drying of the non-woven bag and avoiding the printing ink being blown and deformed.

[0039] When the drying device of the gravure printing machine for non-woven bag processing starts operating, the non-woven bags are first dried through the drying system of conveyor belt 201. After drying, they continue to be conveyed forward. The dried non-woven bags are transferred from conveyor belt 201 to conveyor belt 206. During this process, multiple teeth 202 fixed next to conveyor belt 201 will mesh with the delay gear rod 203 in sequence, thereby driving the rotation of the delay gear rod 203. When the delay gear rod 203 rotates once, the pressing rod 204 fixed on it will press the transmission button of the transmission switch 205 above. The spacing of the teeth 202 corresponds to the spacing of the non-woven bags on conveyor belt 201. Each time the transmission switch 205 is pressed, conveyor belt 206 will move forward a certain distance, thus achieving the effect of transmission and packaging of non-woven bags.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
