Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paper boxes, in particular to a flame retardant treatment device for corrugated paper boxes. Background Art

[0002] Corrugated cardboard is made into corrugated paper boxes through die cutting, indentation, box nailing or gluing. Corrugated paper boxes are the most widely used packaging products, and their consumption has always been the first among various packaging products. This includes calcium plastic corrugated paper boxes. For more than half a century, corrugated paper boxes have gradually replaced transportation packaging containers such as wooden boxes with their superior performance and good processing performance, becoming the main force in transportation packaging. In addition to protecting goods, facilitating warehousing and transportation, it also plays a role in beautifying and promoting goods. Corrugated paper boxes are green environmental protection products, which are beneficial to environmental protection and facilitate loading, unloading and transportation.

[0003] Due to the rapid development of the times, all walks of life attach more and more importance to the requirements for carton packaging. Among them, fireproof and flame retardant corrugated paper boxes have emerged as the times require. By adding flame retardants to the corrugated paper boxes, the corrugated paper boxes can achieve the flame retardant effect. It has been highly recognized by society during the use process.

[0004] The flame retardant treatment of corrugated paper boxes is mainly achieved by using flame retardants. The specific methods include dipping method, coating method, etc.

[0005] The dipping method is to immerse the raw materials of corrugated paper boxes (i.e., corrugated cardboard) in an aqueous solution containing flame retardant, and adjust the flame retardant effect by controlling the dipping time. The flame retardant effect of the paper boxes treated by this method is good. Commonly used flame retardants include ammonium phosphate, water-soluble ammonium polyphosphate, etc.

[0006] At present, when the corrugated paper boxes are subjected to flame retardant treatment by the dipping method, multiple corrugated cardboard sheets are stacked together, and then are pressed into an aqueous solution containing flame retardant by a machine for dipping flame retardant treatment. The main drawback of this method is that due to the fact that the inner corrugated cardboard sheets are stacked together, the aqueous solution containing flame retardant cannot penetrate into them, resulting in the flame retardant treatment of the corrugated cardboard not achieving the ideal effect.

Detailed implementation manners

[0039] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0040] Refer to Figures 1-16, a flame retardant treatment device for corrugated cardboard boxes, including a workbench 1. A dipping tank 2 is arranged on the top of the workbench 1. A bearing plate 3 is arranged above the dipping tank 2. A plurality of uniformly distributed limiting slots 4 are arranged in the bearing plate 3. A corrugated cardboard 5 is inserted in the limiting slot 4. Limiting holes 6 are respectively arranged on both sides of the limiting slot 4. A scraping plate 7 is inserted in the limiting hole 6. And the side surfaces of the two scraping plates 7 in contact with each other are always in sliding contact with the two side surfaces of the corrugated cardboard 5. Support plates 8 are fixedly installed on the inner walls of both sides of the dipping tank 2. The bottoms of the plurality of scraping plates 7 all extend below the limiting holes 6 and are fixedly connected with the support plates 8. The rear side of the bearing plate 3 is connected with a lifting mechanism 9, and the lifting mechanism 9 is used to drive the bearing plate 3 to move up and down.

[0041] In the above embodiment, by arranging a plurality of uniformly distributed limiting slots 4 in the bearing plate 3, since there is a certain distance between two adjacent limiting slots 4, the corrugated cardboard 5 in the limiting slots 4 can be separated from each other, so that the aqueous solution containing the flame retardant can penetrate into it, so as to achieve a better flame retardant treatment effect.

[0042] By arranging scraping plates 7 on both sides of the corrugated cardboard 5, when the corrugated cardboard 5 moves to the lowest position, a small part of the top side of the corrugated cardboard 5 is still between the two scraping plates 7, that is, when the corrugated cardboard 5 moves from the topmost to the lowermost position, it will not break away from between the two scraping plates 7, and when the corrugated cardboard 5 on the bearing plate 3 gradually moves up, under the action of the scraping plates 7, the aqueous solution of the flame retardant is evenly smeared on the surface of the corrugated cardboard 5.

[0043] Specifically, the lifting mechanism 9 includes a bent lifting plate 9a fixedly installed on the rear side of the bearing plate 3. A servo motor 9b is fixedly installed on the workbench 1. A ball screw 9c is fixedly installed on the output end of the servo motor 9b. An adaptation hole is arranged on the side of the bent lifting plate 9a away from the bearing plate 3. A nut seat 9d is fixedly sleeved on the outside of the nut of the ball screw 9c, and the nut seat 9d is fixedly installed inside the adaptation hole.

[0044] In the above embodiment, by the servo motor 9b working to drive the ball screw 9c to rotate, while the ball screw 9c rotates, it drives the nut seat 9d to move up and down in the vertical direction, and the nut seat 9d drives the bent lifting plate 9a and the bearing plate 3 to move synchronously.

[0045] Specifically, a limiting plate 9e is fixedly installed on the top of the workbench 1. A limiting hole 9f is arranged in the limiting plate 9e, and the bent lifting plate 9a is slidably installed in the limiting hole 9f.

[0046] In the above embodiment, the mutual cooperation of the limiting plate 9e and the limiting hole 9f further limits that the bent lifting plate 9a can only move up and down in the vertical direction.

[0047] Specifically, one side of the top of the limit plate 9e is fixedly installed with a fixing plate 9g. A bearing installation hole is provided in the fixing plate 9g, and a bearing 9h is fixedly installed in the bearing installation hole. The top of the screw rod of the ball screw 9c is fixedly installed in the inner ring of the bearing 9h.

[0048] In the above embodiment, the rotation of the screw rod of the ball screw 9c is limited by the bearing 9h, and at the same time, the rotation friction is reduced.

[0049] Specifically, an L-shaped connecting plate 10 is fixedly installed on the bent lifting plate 9a. A baffle 11 is fixedly installed on one side of the L-shaped connecting plate 10 away from the bent lifting plate 9a, and a sponge pad 12 is fixedly installed at the bottom of the baffle 11.

[0050] In the above embodiment, the function of the baffle 11 is to prevent the corrugated cardboard 5 from floating upward due to the upward buoyancy when it is immersed in the aqueous solution containing the flame retardant. The sponge pad 12 is made of soft and elastic material, so it can better protect the corrugated cardboard 5 from being damaged.

[0051] Specifically, support legs 13 are fixedly installed around the bottom of the workbench 1, and a cross plate 14 is fixedly installed between every two adjacent support legs 13.

[0052] In the above embodiment, the bottom of the workbench 1 is supported by the support legs 13, and the cross plate 14 increases the connection firmness between two adjacent support legs 13.

[0053] Specifically, a first reserved slot 15 for the movement of the baffle 11, the sponge pad 12 and the L-shaped connecting plate 10 is provided in the scraper 7.

[0054] In the above embodiment, the function of the first reserved slot 15 is to prevent the baffle 11, the sponge pad 12 and the L-shaped connecting plate 10 from being blocked by the scraper 7 during the downward movement.

[0055] Specifically, a second reserved slot 16 for the movement of the L-shaped connecting plate 10 is provided in the scraper 7.

[0056] In the above embodiment, the function of the second reserved slot 16 is to prevent the L-shaped connecting plate 10 from being blocked by the scraper 7 during the downward movement.

[0057] Working principle: Before the impregnation flame retardant treatment, multiple corrugated cardboard sheets 5 are inserted into the limit slots 4 on the bearing plate 3 one by one. After the corrugated cardboard 5 is installed (as shown in the attachment Figures 1-6As shown in the figure, turn on the servo motor 9b. The operation of the servo motor 9b drives the ball screw 9c to rotate. While the ball screw 9c rotates, it drives the nut seat 9d to move vertically downward. The nut seat 9d drives the bent lifting plate 9a and the bearing plate 3 to move vertically downward. At the same time, the corrugated paperboard 5 on the bearing plate 3 also moves downward and gradually immerses into the impregnation tank 2 containing the flame retardant aqueous solution. When the corrugated paperboard 5 moves to the bottom (as shown in the appendix Figure 15 , 16 shown), the servo motor 9b stops working. At this time, the corrugated paperboard 5 is completely immersed in the impregnation tank 2 for flame retardant treatment. And in this state, a small part of the top side of the corrugated paperboard 5 is still between the two scraping plates 7 (which can be clearly seen from the appendix Figure 16 ). That is, during the process of the corrugated paperboard 5 moving from the top to the bottom, it will not break away from between the two scraping plates 7. That is, under the limiting action of the two scraping plates 7, it is ensured that there is no offset during its movement. In addition, since the L-shaped connecting plate 10, the baffle 11 and the sponge pad 12 move synchronously with the bent lifting plate 9a, therefore, under the blocking action of the sponge pad 12 and the baffle 11, the corrugated paperboard 5 will not float upward under the action of buoyancy. After the flame retardant treatment of the corrugated paperboard 5 is completed, start the servo motor 9b again. The operation of the servo motor 9b drives the ball screw 9c to rotate. While the ball screw 9c rotates, it drives the nut seat 9d to move vertically upward. The nut seat 9d drives the bent lifting plate 9a and the bearing plate 3 to move vertically upward. At the same time, the corrugated paperboard 5 on the bearing plate 3 also gradually moves upward. Under the action of the scraping plate 7, the flame retardant aqueous solution is evenly applied to the surface of the corrugated paperboard 5.

[0058] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
