Description

Technical Field

[0001] The invention belongs to the field of paraffin processing, and specifically relates to a method for preparing flaky paraffin, and in particular to a method for preparing flaky paraffin that is not easy to accumulate. Background Art

[0002] Because paraffin wax is soft and prone to clumping during storage, it is inconvenient to use. However, paraffin wax flakes offer the advantages of being able to store without clumping and be easily packaged. Therefore, most paraffin wax is manufactured in flake form. Conventional flake manufacturing involves injecting liquid wax into a mold to form a wax block of a certain mass, which is then cut into flakes. This production process requires a large number of molding molds, which themselves take up a significant amount of production space. After molding, manual packaging is also required, making the overall process time-consuming and labor-intensive.

[0003] CN205443156U discloses a pressure-sensing slicing paraffin product production system, including a hydrogenated oil storage tank, a loose wax storage tank, a wax paste storage tank and a semi-refined storage tank, the hydrogenated oil storage tank is connected to the first storage tank, the loose wax storage tank is connected to the filter press, the slicing molding device includes a base, a conveyor and a bracket are installed on the upper part of the base, a push rod motor and a control device are installed on the side of the bracket, a pressure-sensitive sensor is installed at the push-pull rod end of the push rod motor, a mold is installed at the lower part of the pressure-sensitive sensor, the mold can cooperate with the conveyor, and the control device connects the pressure-sensitive sensor and the push rod motor through a wire. The control device adjusts the output power of the push rod motor according to the electrical signal, so that the output power of the push rod motor is kept within a reasonable range, which not only avoids incomplete cutting of paraffin products, but also avoids the mold scratching the conveyor belt of the conveyor. However, this production system still has the problem of requiring a large number of molding molds.

[0004] Since the current production process of flaky paraffin requires a large number of molds and has the problem of occupying space, how to provide a flaky paraffin production method that takes up less space has become an urgent problem to be solved. Summary of the Invention
