[0028] As shown in the attached figure, the present invention includes a wax melting storage tank 1, a wax liquid conveying filter 2, and a filling machine 3 connected sequentially from front to back. The wax melting storage tank 1 includes a tank body 5 and a heating device. The tank body 5 is divided into upper and lower parts by a perforated partition 6. A drain pipe and a water inlet pipe are respectively provided on the lower part of the tank body 5. The heating device includes a central heating pipe 7 coaxially installed in the tank body 5 and a set of outer heating pipes 8 arranged in a ring around the central heating pipe 7. The set of outer heating pipes 8 are respectively connected to the central heating pipe 7 through two sets of connecting pipes 9.

[0029] Liquid wax or wax blocks are stored in the melting wax storage tank 1 and are easily transported and filled after melting. A perforated partition 6 separates the wax blocks at the top. Water is filled into the tank body 5 located below the perforated partition 6, with the water level not exceeding two-thirds of the lower part of the tank body 5. The heating device heats both water and wax simultaneously, causing the wax to float on the water surface. The drain pipe is located above the water level, draining the wax without carrying water out. The central heating pipe 7, the outer heating pipe 8, and the connecting pipe 9 form a three-dimensional heating system, capable of simultaneously heating the upper and lower layers of wax within the entire tank body 5, improving melting efficiency. Furthermore, since there is no stirring device, the water and wax do not flow in the molten state, allowing impurities to settle at the bottom for easy separation.

[0030] The wax delivery filter 2 includes a pair of filter tanks 20. The filter tanks 20 are equipped with heating coils 21, and a detachable filter cartridge 22 is provided inside the heating coils 21. The top of the filter tanks 20 is equipped with a cover 23 for pressing the filter cartridge 22. The liquid inlets of the pair of filter tanks 20 are connected to the liquid outlet of the tank body 5 through a liquid inlet tee pipe 24, and the liquid outlets of the pair of filter tanks 20 are connected to the liquid inlet of the filling machine 3 through a liquid outlet tee pipe 26. Both the liquid inlet tee pipe 24 and the liquid outlet tee pipe 26 are equipped with a three-way solenoid valve 27.

[0031] The two filter tanks 20 are connected in parallel. The wax liquid enters one of the filter tanks 20 through the inlet three-way pipe 24. After being filtered through the filter cartridge 22, the wax liquid is discharged from the outlet three-way pipe 26. When the filter cartridge 22 needs to be cleaned, the three-way solenoid valve 27 on the inlet three-way pipe 24 and the outlet three-way pipe 26 is activated, which reverses the flow so that the wax liquid flows through the other filter tank 20. Then the first filter tank 20 can be opened and the filter cartridge 22 can be taken out for cleaning.

[0032] The filling machine 3 includes a wax tank 40, a conveyor roller 41, an anti-drip wax spray head 42, and a wax receiving box 43. The wax tank 40 has multiple filling heads 45 located above the conveyor roller 41 on one side. The anti-drip wax spray head 42 and the wax receiving box 43 are symmetrically installed on both sides of the filling head 45.

[0033] The filtered wax liquid enters the wax tank 40, which is connected to a heating tube to maintain a certain temperature. The packaging box moves from the conveyor roller 41 to below the filling head 45 and stops. The filling head 45 starts to fill the corresponding packaging boxes. After filling is completed, the filling head 45 closes, and the anti-drip wax spray head 42 is connected to the high-pressure pump to provide high-pressure air. Then the anti-drip wax spray head 42 opens, forming a horizontal air curtain below the filling head 45. If wax droplets fall, they will be blown horizontally into the wax receiving box 43 when they hit the air curtain, preventing wax droplets from falling onto the packaging box or the conveyor roller 41. After the anti-drip wax spray head 42 is opened, the conveyor roller 41 moves forward a distance to move the next batch of packaging boxes to the corresponding filling position. The anti-drip wax spray head 42 closes, and the next batch of filling begins.

[0034] Furthermore, a drain pipe is provided at the bottom of the tank 5, and one end of the bottom of the central heating pipe 7 passes through the perforated partition 6 and extends to the outside of the tank 5. When the machine is stopped, the drain pipe can be opened to drain the water and sediment in the tank 5, and water can be refilled at the same time to maintain the water level in the tank 5.

[0035] Furthermore, a throttling plate 10 is provided in the central heating pipe 7 located between the upper and lower sets of connecting pipes 9. Both the upper and lower ends of the outer heating pipe 8 are closed, and one bottom end of the outer heating pipe 8 is connected to the central heating pipe 7 through the return pipe 12.

[0036] The throttling plate 10 reduces the diameter of the central heating pipe 7, blocking the steam entering the central heating pipe 7. As a result, the steam is dispersed from the lower connecting pipe 9 into the outer heating pipes 8, and then enters the upper part of the central heating pipe 7 through the upper connecting pipe 9. This allows the steam to flow in the central heating pipe 7, the outer heating pipes 8, and the connecting pipe 9, resulting in uniform heating. The condensate in the upper part flows back through the holes of the throttling plate 10. Preferably, the opening diameter of the throttling plate 10 is no more than 10 mm. When the condensate flows back, the opening of the throttling plate 10 can be reduced or blocked, allowing more steam to disperse into the lower connecting pipe 9 and reducing energy consumption.

[0037] The diameter of the return pipe 12 is smaller than that of the central heating pipe 7 and the outer heating pipe 8. It is mainly used for the condensate from each outer heating pipe 8 to return to the central heating pipe 7.

[0038] Preferably, there are 6 outer heating tubes 8, the connecting pipes 9 between two outer heating tubes 8 located in opposite directions are at the same height, and the connecting pipes 9 on two adjacent outer heating tubes 8 are staggered vertically.

[0039] That is, the connecting pipe 9 between the two opposite outer heating pipes 8 is connected to form a straight pipe, so that the steam can be evenly distributed into the two opposite outer heating pipes 8. The straight pipes are not at the same height, so they can heat wax blocks at different heights.

[0040] Furthermore, the filter tank 20 is provided with a ring of filter cartridge mounting protrusions, and the top opening of the filter cartridge 22 is provided with a ring of rim. The filter cartridge 22 is movably inserted into the filter tank 20 and pressed tightly by the cover 23.

[0041] The cover 23 is fastened to the filter tank 20 by a set of screws. A set of positioning rods is arranged in a ring at the bottom of the cover 23, and a compression spring 28 is sleeved on the positioning rod. The filter cylinder 22 is pressed by a set of compression springs 28.

[0042] The compression spring 28 abuts against the filter cartridge 22. The number of compression springs 28 is the same as the number of screws, so that the top of the filter cartridge 22 is subjected to uniform force in all directions, and can fit more tightly with the filter canister 20.

[0043] The filter cartridge 22 is equipped with a handle at the top for easy handling.

[0044] Preferably, the two heating coils 21 are connected in parallel via a pipe. When one of the filter tanks 20 is not in operation, the heating coil 21 continues to heat it to maintain the internal temperature and prevent the wax from solidifying.

[0045] Preferably, the wax collection box 43 has an L-shaped structure, and a liquid collection groove is provided at the bend of the L-shape, with a drain pipe on one side of the liquid collection groove. During installation, the horizontal bottom surface of the wax collection box 43 should be lower than the height of the anti-drip wax spray head 42, so that the blown wax droplets can completely enter the wax collection box 43, and the wax liquid can smoothly enter the liquid collection groove for collection under the opposing air pressure inside the wax collection box 43.

[0046] Furthermore, a splash guard 46 is provided inside the wax collection box 43. The splash guard 46 can effectively prevent wax droplets from colliding and splashing out inside the wax collection box 43.
