A stirring shaft 25 and a feed pipe 262 are provided inside the spray tank 2, and an electric heating ring 263 is mounted on the outer wall of the feed pipe 262. The upper end of the feed pipe 262 is connected to a spray pump 26. One end of the stirring shaft 25 is connected to a motor 24, and the motor 24 is fixed to the outer wall of the spray tank 2. An arc plate with a perforated structure is welded to the outer wall of the stirring shaft 25. The output port end of the spray pump 26 is connected to the vertical pipe 21 through the discharge pipe 261. At the same time, a thermostat is provided on the outer wall of the spray tank 2, and the thermostat is connected to the electric heating ring 263.
[0021] In this embodiment, the base 1 and the spray tank 2, as well as the upper structure of the base 1 constitute the food packaging box waterproof coating sprayer involved in this application, which is used for the outer waterproof coating spraying process of the food packaging box (carton).
[0022] Specifically, the outer sides of the active roller 13 and the passive roller 14 are both made of rubber material, so as to have an elastic squeezing and friction effect on the packaging box cardboard, thereby facilitating the transportation of the cardboard.
[0023] Specifically, the electric heating ring 263 is configured as a spiral structure, and can also heat the feed pipe 262 during heating, so as to ensure that the waterproof coating passing through the feed pipe 262 is in a uniform solution state.
[0024] As a preferred embodiment, the stirring shaft 25 is located at the bottom of the spray tank 2, and the stirring shaft 25 and the perforated arc plate facilitate uniform stirring of the waterproof coating to prevent precipitation from causing uneven spraying.
[0025] like Figure 1 and Figure 3As shown, a driving assembly 15 is provided on the upper side of the side plate 12, and the driving assembly 15 is connected to the core shaft inside the active roller 13, a slide groove 121 is opened inside the side plate 12, and the upper and lower end roller shafts 141 of the passive roller 14 are slidably connected in the slide groove 121, and the outer wall of the roller shaft 141 is rotatably connected with a rotary handle screw 122, a pair of vertical pipes 21 are provided, and the nozzles of the side nozzles 211 are arranged oppositely, and the side nozzles 211 are provided with multiple groups arranged equidistantly in the vertical direction, the upper and lower positions of the upper nozzles 221 and the lower nozzles 231 correspond, and the upper nozzles 221 and the lower nozzles 231 are located between the active roller 13 and the passive roller 14.
[0026] Specifically, the handle screw 122 is turned to facilitate the driving roller shaft 141 to move in the slide groove 121, thereby facilitating the adjustment of the gap between the driving roller 13 and the driving roller 13 to adapt to paperboards of different thicknesses.
[0027] It should be noted that the width of the groove 11 is much greater than the thickness of various paperboards, and when the distance between the active roller 13 and the passive roller 14 changes, the upper and lower side edges of the paperboard are still within the spraying range of the upper nozzle 221 and the lower nozzle 231.
[0028] When in use, the cardboard of the food packaging box is folded into a flat state, and then inserted between the active roller and the passive roller between the side panels, and the driving assembly and the spray pump are started at the same time. The cardboard is driven forward by the active roller and the passive roller, and the bottom edge of the cardboard is located in the groove. Then, when the cardboard leaves the side panel, the left and right sides of the cardboard are sprayed by the side nozzles, and the upper and lower sides of the cardboard are sprayed by the upper nozzle and the lower nozzle respectively, thereby achieving comprehensive spraying of the cardboard. During the spraying process, the motor on the outer wall of the spray tank is started, so that the motor drives the stirring shaft to drive the perforated arc plate to rotate, thereby preventing the waterproof coating inside the spray tank from sedimentation and evenly stirring it. At the same time, the electric heating coil is controlled by the thermostat to heat the waterproof coating, thereby preventing the coating from solidifying when used in winter.
[0029] The food packaging box waterproof coating sprayer of the utility model can effectively solve the problems of incomplete spraying of the packaging box by the existing packaging box sprayer and the waterproof coating is easy to solidify or precipitate, resulting in unevenness. It further enhances the comprehensiveness and uniformity of spraying the food packaging box waterproof coating on the basis of the existing food packaging box waterproof coating sprayer technology, and at the same time has the effect of preventing the adverse phenomena of precipitation and coagulation, thereby ensuring the quality of spraying.
