[0002] Waxing machine (also known as waxing machine) is a kind of equipment specially designed to coat a layer of wax protective film on the surface of various objects, and is widely used in the packaging protection of refrigerated products, fruits and vegetables and food fields, to effectively prevent the invasion of moisture and ensure the preservation quality and prolong the shelf life of products.In practical application, a common use mode is to coat a layer of paraffin wax on corrugated board to form an effective waterproof barrier.

[0003] The specific operation process includes first pouring liquid paraffin evenly on the surface of corrugated board, and then making paraffin fully penetrate and firmly adhere to corrugated board by the action of rolling wheel.In order to accelerate the solidification process of paraffin, cooling water is usually sprayed on the surface of paraffin immediately after coating, and then the excess water is removed after the paraffin is completely solidified.However, in this process, due to the high viscosity of paraffin, it is easy to adhere to the rolling wheel during rolling, which not only causes uneven surface of paraffin layer, but also directly affects the waxing effect of subsequent products if the paraffin remaining on the rolling wheel is not cleaned in time, thereby reducing production efficiency and product quality.

[0004] In view of the above problems, the existing waxing machine is equipped with a certain cleaning device to help remove the residual paraffin on the rolling wheel.However, most of these cleaning mechanisms adopt fixed installation mode, which not only increases the difficulty of daily maintenance and cleaning work, but also limits the improvement space of cleaning effect.

[0005] Therefore, the present application aims to improve the working efficiency of waxing machine, ensure the coating quality, simplify the maintenance process and reduce the production cost.

The scraper disc 62, away from the hinged position of the fixed overturning seat 61, forms a scraper side 63 with a sharp edge on one side, and the top surface thereof extends in the direction from the scraper side 63 to the hinged position of the fixed overturning seat 61 to form a guide groove 64. The guide groove 64 is used for guiding the paraffin scraped from the roll coating roller to the bottom of the scraper side 63. The receiving disc 70 is detachably arranged between the side walls on both sides of the rack 10 and located directly below the guide groove 64. The upper end surface of the receiving disc 70 forms a wax collecting groove 71 for collecting paraffin.

[0047] Preferably, as Figure 3 , 4As shown in Figure 6, the edge of the scraper side 63 is recessed inward to form a mounting hole 65, and a heating scraper 66 is detachably arranged in the mounting hole 65. The heating scraper 66 has a metal blade section extending along the top edge of the guide groove 64 and a main body section (not shown in the figure) connected to the metal blade section. An electric heating module is provided in the main body section, and the output heating end of the electric heating module is connected to the metal blade section to achieve heat conduction.
