Description

Technical Field

[0001] This utility model relates to the field of woven bag printing technology, specifically to a reverse printing drying oven mechanism. Background Technology

[0002] Flexographic woven bags are woven bag products made using flexographic printing technology. They employ a flexible printing method and use a raised, elastic rubber plate as the printing plate. The manufacturing process includes steps such as bonding plywood to rollers, pouring ink into ink cartridges, and starting the printing press. During printing, the pattern is transferred to the surface of the flexographic woven bag by supplying ink through an anilox roller.

[0003] Currently, the commonly used reverse printing ovens for flexographic woven bags are installed on the printing mechanism, which has space limitations and a small air volume per oven, failing to achieve the desired reverse printing drying effect. Therefore, we propose a reverse printing oven mechanism. Summary of the Invention

[0004] The purpose of this invention is to overcome the aforementioned problems in the prior art and provide a reverse printing drying oven mechanism that enhances the reverse printing drying effect and solves the problem of unsatisfactory reverse printing drying effect.

[0005] To solve the above technical problems, this utility model provides a reverse printing oven mechanism, including an intermediate material feeding frame, a fan and a heating pack. A long oven is arranged in the middle of the intermediate material feeding frame, a front guide roller assembly is arranged on the left side of the long oven, and a rear guide roller assembly is arranged on the right side of the long oven. The long drying oven has an inlet on its left side wall and an outlet on its right side wall. The heating pack is connected to the output end of the fan. One side of the long oven is connected to an air inlet, and the other end of the heating pack is provided with an air outlet. The air outlet and the air inlet are connected by a connecting pipe.

[0006] Preferably, the front guide roller assembly and the rear guide roller assembly have the same structure.

[0007] Based on the above technical features, the guide roller assembly is easy to use, eliminating the need for additional components and saving costs.

[0008] Preferably, the front guide roller assembly includes a guide roller, and both ends of the guide roller are fixedly connected to a support shaft.

[0009] Based on the above technical features, the guide roller is supported.

[0010] Preferably, the ends of the two sets of support shafts that are far apart from each other are rotatably connected to bearing seats via bearings, and the bearing seats are fixedly installed on the top of the intermediate material feeding frame.

[0011] Based on the above technical features, it is easy for the guide roller to rotate on the bearing housing.

[0012] Preferably, a long air duct is provided on one side wall of the intermediate material feeding rack, and the long air duct is connected to the air inlet.

[0013] Based on the above technical features, it is easy to deliver hot air into the long air duct through the air inlet.

[0014] Preferably, the side wall of the elongated air duct away from the air inlet is uniformly connected to an air outlet pipe.

[0015] Based on the above technical features, it is easy to evenly deliver hot air from the long air duct to the air outlet pipe.

[0016] Preferably, the other end of the air outlet pipe is sealed, and air outlet nozzles are evenly distributed on the top of the air outlet pipe along its length.

[0017] Based on the above technical features, the evenly distributed air outlet pipes and the evenly distributed air outlet nozzles on the air outlet pipes facilitate the delivery of hot air to the bottom of the long oven, and make the hot air evenly fill the bottom of the long oven.

[0018] In summary, this utility model has at least one of the following beneficial effects: This invention solves the problem of unsatisfactory reverse printing drying effect by setting a long drying oven inside the original intermediate material feeding rack, and by coordinating the air inlet, connecting pipe, air outlet, heating pack and fan. This not only does not change the original machine structure, but also enhances the reverse printing drying effect. Attached Figure Description

Figure 2 ; The attached diagram lists the components represented by each number as follows: 1-Front guide roller assembly, 2-Intermediate material feeder, 3-Rear guide roller assembly, 4-Long drying oven, 5-Air inlet, 6-Connecting pipe, 7-Air outlet, 8-Heating pack, 9-Fan. Detailed Implementation

[0020] The following is in conjunction with the appendix Figures 1-2 The present invention will be described in further detail below.

[0021] One embodiment of this utility model is shown below: Figure 1 and Figure 2A reverse printing oven mechanism includes an intermediate material feeding frame 2, a fan 9 and a heating pack 8. A long oven 4 is arranged in the middle of the intermediate material feeding frame 2. A front guide roller assembly 1 is arranged on the left side of the long oven 4 and a rear guide roller assembly 3 is arranged on the right side of the long oven 4. The long drying oven 4 has an inlet on its left side wall and an outlet on its right side wall; The heating pack 8 is connected to the output end of the fan 9. One side of the long oven 4 is connected to the air inlet 5, and the other end of the heating pack 8 is provided with the air outlet 7. The air outlet 7 and the air inlet 5 are connected by the connecting pipe 6. The front guide roller assembly 1 and the rear guide roller assembly 3 have the same structure, which makes it convenient to use the guide roller assembly. There is no need to add any additional parts, saving costs. The front guide roller assembly 1 includes a guide roller. Both ends of the guide roller are fixedly connected to support shafts to support the guide roller. The ends of the two sets of support shafts that are far apart from each other are rotatably connected to bearing seats through bearings. The bearing seats are fixedly installed on the top of the intermediate material feeding frame 2, which facilitates the support of the guide roller and its rotation on the bearing seats. A long air duct is provided on one side wall of the intermediate material rack 2. The long air duct is connected to the air inlet 5, which facilitates the delivery of hot air into the long air duct through the air inlet 5. The long air duct initially delivers hot air evenly along its length. An air outlet pipe is evenly connected to the side wall of the long air duct away from the air inlet 5. The other end of the air outlet pipe is sealed. Air outlet nozzles are evenly opened on the top of the air outlet pipe along its length. Through the evenly distributed air outlet pipes and the evenly opened air outlet nozzles on the air outlet pipes, it is convenient to deliver hot air to the bottom of the long oven 4 and make the hot air evenly fill the bottom of the long oven 4.

[0022] Working principle: After the reverse side of the material is printed, it passes through the printing mechanism along the guide roller to the front guide roller assembly 1 of the intermediate material feeding frame 2. After the hot air from the air outlet of the long drying oven 4 dries the material, it reaches the rear guide roller assembly 3, and then passes through the material feeding and winding mechanism from here. The hot air from the air outlet of the long drying oven 4 is delivered by the fan 9 from the air outlet 7 through the connecting pipe 6 and then through the air inlet 5 to the long drying oven 4. Since the reverse printing surface of the material does not come into contact with the guide roller during this period, and is dried by the long drying oven 4, the ideal drying effect is finally achieved.

[0023] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
