Description

Technical Field

[0001] This utility model relates to the field of composite wax production technology, specifically to a composite wax filtration and filling system. Background Technology

[0002] Composite wax is a waxy substance composed of multiple different components, which are achieved by mixing and melting different components. In the preparation process, impurities in the wax need to be filtered before filling. The existing wax liquid filter cylinder screen needs to be cleaned by stopping the machine, which affects the production progress. During the filling process, a wax receiving plate extends under the filling head. The wax receiving plate needs to be cleaned frequently, otherwise wax droplets will still fall when it moves back and forth frequently. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0020] In the description of the embodiments of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the utility model. Furthermore, if terms such as "first" or "second" appear in the description of this utility model, they are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0021] In the description of the embodiments of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] As shown in the attached drawings, this utility model includes a wax liquid conveying filter 2 and a filling machine 3. The wax liquid conveying filter 2 includes a pair of filter tanks 20. A heating coil 21 is provided inside the filter tank 20, and a detachable filter cartridge 22 is provided inside the heating coil 21. A cover 23 for pressing the filter cartridge 22 is provided on the top of the filter tank 20. The liquid inlets of the pair of filter tanks 20 are connected by a liquid inlet tee pipe 24. The liquid outlets of the pair of filter tanks 20 are connected to the liquid inlet of the filling machine 3 by a liquid outlet tee pipe 26. A three-way solenoid valve 27 is provided on both the liquid inlet tee pipe 24 and the liquid outlet tee pipe 26.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] The filter cartridge 22 is equipped with a handle at the top for easy handling.

[0030] 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.

[0031] 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.

[0032] 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.
