Description

Technical Field

[0001] The utility model belongs to the field of carton preparation devices, and in particular relates to a carton wax pouring production line. Background Art

[0002] Wax-impregnated cartons are made by taking advantage of the wax's insoluble, non-toxic, harmless and non-polluting properties. They are made through a physical process of wetting and baking. This does not change the chemical properties of the wax, but allows the wax to be evenly distributed on the surface of the carton and its joints, forming a certain protective layer that isolates water from the carton matrix, achieving moisture-proof and water-resistant effects.

[0003] Its production equipment mainly consists of a large wax pool and wax dipping frame, plus a wax removal production line. During production, cartons are first loaded into the frame, and then the cartons are immersed in the wax pool one by one, and then lifted up. Then, the cartons are manually separated one by one and hung on iron hooks, and then the iron hooks are hung on the wax removal production line. The wax removal production line takes them into an oven with hot air to heat them, melt the solidified wax, and let the wax slowly flow down to achieve the purpose of removing excess wax. The waxed cartons are then manually removed and placed upright on the shelf. After the wax on the cartons cools and solidifies, they are packaged and put into storage. The production efficiency of such production equipment is very low, with an output of about 200 to 300 wax-impregnated cartons per hour. In addition, the labor intensity of the workers is high, the wax dripping on the ground is seriously wasted, and the energy consumption is also high. In addition, the quality of the wax-impregnated cartons produced is uneven, and the local dewaxing is serious, resulting in poor waterproof ability, which makes it easy for the boxes to collapse, causing relatively large economic losses to customers.

[0031] The wax sprinkling device 2 is used to spray wax on the cartons stretched on the conveyor belt 12, and includes a spraying mechanism 21 arranged in the first shell 14 opposite to the conveyor belt 12, a recovery mechanism 22 arranged at the bottom of the first shell 14 for recovering the wax liquid, and a wax liquid supply mechanism 23 connected to the spraying mechanism 21. The carton stretched on the conveyor belt 12 is sprayed by the spraying mechanism 21 so that the wax liquid can be smoothly sprayed into the inner and outer surfaces of the carton.

[0032] The spray mechanism 21 includes a plurality of spray curtains 211 arranged at intervals inside the first housing 14 and opposite to the conveyor belt 12, a plurality of delivery branch pipes 212 arranged at the top of the first housing 14 and connected to the plurality of spray curtains 211, a delivery main pipe 213 connected between the plurality of delivery branch pipes 212 and the wax liquid supply mechanism 23, and two guide plates 214 arranged relatively inside the first housing 14 and located on both sides of the conveyor belt 12.

Furthermore, a guide plate 214 is arranged obliquely downward inside the first shell 14, and its lower end extends downward to below the top of the propping mechanism 13. By providing the guide plate 214, the wax liquid sprayed on the inner wall of the first shell 14 is guided to flow downward to the recovery mechanism 22.

[0033] The recovery mechanism 22 includes two liquid receiving grooves 221 spaced apart at the bottom of the first shell 14, a recovery pool 222 disposed between the two liquid receiving grooves 221, and two liquid guiding members respectively disposed between the liquid receiving grooves 221 and the recovery pool 222, wherein one end of the liquid receiving groove 221 is connected to the end of the first shell 14 and the other end extends inward, a gap is formed between the two liquid receiving grooves 221, and the recovery pool 222 is disposed below the gap; specifically, the liquid guiding member includes a liquid guiding plate 223 disposed obliquely downward at the end of the liquid receiving groove 221 and opposite to the recovery pool 222; when wax is poured, the excess wax liquid in the wax pouring process is recovered through the two liquid receiving grooves 221, and is sent to the recovery pool 222 for recycling through the guidance of the liquid guiding plate 223.

[0034] The wax liquid supply mechanism 23 includes a wax liquid storage tank 231 connected between the recovery tank 222 and the spray mechanism 21 and a delivery pump 232 arranged in the wax liquid storage tank 231 .

[0035] The heat-insulating wax infiltration mechanism 3 is located behind the spray mechanism 21 and is connected to the first shell 14 to supply hot air to the inside of the first shell 14. It includes a heat-evening chamber 31 connected to the inside of the first shell 14 and a burner 32 for supplying heat to the inside of the heat-evening chamber 31. Specifically, the heat-evening chamber 31 includes a heat-evening chamber body 33, an air inlet end 34 arranged at the front end of the heat-evening chamber body 33 and connected to the burner 32, and an air outlet end 35 connecting the heat-evening chamber body 33 and the inside of the first shell 14. The heat-evening chamber body 33 is respectively provided with two connecting parts 331 connected to the air inlet end 34 or the air outlet end 35, and the diameter of the connecting part 331 gradually decreases from the end of the heat-evening chamber body 33 to the outside; by limiting the structure of the heat-evening chamber 31, the incoming hot air is first mixed evenly in the heat-evening chamber 31 and then sent to the first shell 14 to perform heat-insulating treatment on the carton after waxing, so that the wax liquid on the surface of the carton infiltrates the carton in all directions to ensure the production quality of the carton.

[0036] The cooling device 4 is arranged on the second shell 15 opposite to the conveyor belt 12, and cools the cartons that have been waxed.

[0037] During operation, the carton is first opened on the opening mechanism 13 and conveyed to the bottom of the spray mechanism 21 along the conveyor belt. The spray mechanism 21 performs wax treatment on the incoming carton. The carton after wax treatment continues to move along the conveyor belt 12, and the hot air provided by the thermal insulation wax infiltration device 3 makes the wax liquid on the surface of the carton fully penetrate the carton; then, cold air is conveyed into the second shell 15 through a plurality of cooling fans 41 arranged at intervals in the conveying direction to cool the carton entering the second shell 15, so that the wax liquid on the carton solidifies into a solid state and reaches a degree that it can be stacked without sticking together, thereby completing the entire wax-impregnated carton production.

[0038] The wax pouring production line defined in the present application has a compact overall structure and integrates wax pouring, heat preservation, cooling and solidification into one production line, effectively reducing the space occupied by the equipment, achieving the goal of automated production, greatly improving production efficiency and the quality of cartons, ensuring the stability of mass production of cartons, and requiring no human intervention in the intermediate process, which greatly reduces the labor intensity of operators.
