Description

Technical Field

[0001] The utility model belongs to the technical field of wax pill automatic forming machines, in particular to an automatic wax pill forming machine. Background Art

[0002] The wax-type temperature sensing element is provided with a temperature sensing wax package, which is currently processed and manufactured manually to form a wax pellet for use. Fig.16 As shown, the existing temperature-sensitive wax package or sensor is made by wax pellet processing technology, specifically, the mixed wax is made into temperature-sensitive wax and crushed, and then extruded to form wax columns, followed by weighing, preheating and punching. The wax pellet crushing produces a lot of dust and noise, which will affect human health. In order to ensure that the weight of the wax pellet is within a controllable range, it is necessary to manually cut it with a knife or add wax powder for weighing. The process is complicated and inefficient, and multiple processes require multiple people to complete together.

[0003] It can be seen that the existing technical solutions have the following disadvantages: (1) long processes, many equipments, many operators, and large production sites; (2) the production environment of some processes is harsh, which has an impact on the health of personnel, and they need to wear special protective clothing, and the physical comfort of operators is relatively low; (3) the production cost is high and the efficiency is low; therefore, the present technical solution provides a method of cooling the mixed wax into a wax column in an inverted and fixed mold, and placing the wax column in a storage box of an automatic molding machine of the present technical solution. The equipment enters the wax ball automatic molding mechanism through an automatic feeding and heating system, and after passing through the temperature, pressure and high-precision mold cavity and cooling system, a wax ball with holes that meets the weight is formed and can be used directly; thus, an automatic wax ball molding machine is proposed. Utility Model Content

[0004] The utility model provides a wax pill automatic forming machine, which is composed of a material storage box, a preheating pipeline, a heating forming cylinder, a wax pill material return mechanism, a machine tool frame and other structures. Columnar wax cakes are manually stacked in a material discharge box, and the wax column is pushed to the end of the first preheating material channel by a first pushing cylinder, and the end of the second preheating material channel is controlled by a blocking cylinder to drop to the drainage guide groove and the storage cavity position in sequence. When there is no paraffin in the heating forming cylinder, the main cylinder piston is withdrawn, and the blocking cylinder of the second preheating material channel is opened to send a preheated columnar wax cake into the heating forming cylinder for drainage. In the material channel, the main cylinder piston extends out to press the wax cake in the drainage channel into the heated molding cylinder to make wax pills; at the same time, the wax pushing cylinder retreats, and a cold columnar wax cake is sent out of the storage box. The pushing cylinder extends out to add a wax cake to the preheating oven for preheating, and a batch of wax cakes is added manually after there is no wax cake in the storage box. Fully automated production can be achieved, and weighing can be eliminated, thereby improving product quality, reducing labor costs, reducing noise, and improving operating comfort.
