[0014] Figure 1 The schematic diagram of the structure is a stearic acid alcohol-based solid alcohol automatic molding equipment. DETAILED DESCRIPTION

[0015] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] like Figure 1 As shown, an automatic molding device for stearic acid alcohol-based solid alcohol includes a stearic acid alcohol-based alcohol liquid pipeline 1, the stearic acid alcohol-based alcohol liquid pipeline 1 is connected to one end of a feeding pump 2, the other end of the feeding pump 2 is connected to one end of a feeding pipeline 3, the other end of the feeding pipeline 3 is respectively connected to the inlets of multiple molding tubes 4 through multiple branch pipelines, the surfaces of the multiple molding tubes 4 are provided with cooling water jackets 5, each branch pipeline is provided with a solenoid valve 6, and the outlets of the multiple molding tubes 4 are provided with slicers 7.

[0017] Preferably, a photoelectric switch 8 for detecting the discharge is also provided at the outlet of the forming tube 4, and the photoelectric switch 8 is interlocked with the blade driving device of the slicer 7. With this design, the photoelectric switch 8 can detect whether there is stearic acid alcohol-based alcohol solid discharge at the outlet of the forming tube 4. After detecting the stearic acid alcohol-based alcohol solid discharge, the driving device of the slicer 7 drives the blade to slice the stearic acid alcohol-based alcohol solid; in this embodiment, the slicer 7 can adopt a commonly used slicing device such as a rotary slicer.

[0018] Preferably, the plurality of solenoid valves 6 are all connected to a PLC controller 9. The PLC controller 9 can set the time for the plurality of solenoid valves 6 to be opened and closed in sequence, thereby continuously switching the molds to perform the injection molding process.

[0019] Preferably, the surface of the cooling water jacket 5 is connected to a cooling water inlet pipeline 5.1 and a cooling water outlet pipeline 5.2 respectively. Cold water can be continuously supplied to the cooling water jacket 5 through the cooling water inlet pipeline 5.1 and the cooling water outlet pipeline 5.2. The cold water in this embodiment is water in a cooling tower. The cooling water inlet pipeline 5.1 and the cooling water outlet pipeline 5.2 are provided with valves to control the opening and closing process of the cooling water.

[0020] Preferably, the surface of the cooling water jacket 5 is also connected to the hot water inlet pipeline 5.3 and the hot water outlet pipeline 5.4 respectively. Hot water can be supplied to the cooling water jacket 5 through the hot water inlet pipeline 5.3 and the hot water outlet pipeline 5.4. Before the stearic acid alcohol-based alcohol liquid is introduced, the valves on the hot water inlet pipeline 5.3 and the hot water outlet pipeline 5.4 on the surface of all cooling water jackets 5 can be opened in advance, and hot water is introduced into the cooling water jacket 5, so that the stearic acid alcohol-based alcohol solids remaining in the last batch of production process in the molding tube 4 are melted. For example, there are corresponding production tasks every day. After the first production task is completed, the entire molding equipment is stopped, and stearic acid alcohol-based alcohol solids will remain in the molding tube 4. When a new batch of production process is started for the second time, if the stearic acid alcohol-based alcohol solids remaining in the molding tube 4 are not cleaned, it will affect its molding process; so it is necessary to introduce hot water in advance for the melting process. In this embodiment, the preheating step is usually performed when the next production is carried out after a long interval between the last production. For example, the interval between two productions is generally more than 12 hours or the interval is more than 4 hours in winter when the temperature is low.

[0021] Preferably, the feed line 3 is also connected to a reflux line 10, and a valve is provided on the reflux line 10. When a blockage or abnormality occurs inside a certain molding tube 4, causing the stearic acid alcohol-based alcohol liquid to be unable to enter the molding tube 4, the internal pressure of the entire feed line 3 will increase. By opening the valve on the reflux line 10, the pressure can be released in time to ensure a safe production process.

[0022] More preferably, the outlet end of the forming tube 4 is also provided with a sealing valve plate that can be opened and closed, the driving device of the sealing valve plate is connected to the PLC controller 9, and a one-way exhaust hole is also provided on the surface of the forming tube 4. In this embodiment, the reason for designing the sealing valve plate is that when the forming is started for the first time every day or each batch, the outlet section of the forming tube 4 must be blocked to prevent the stearic acid alcohol-based alcohol liquid that enters the forming tube 4 from flowing out directly without being formed. Therefore, before the first forming, the outlet section of the forming tube 4 needs to be blocked. After the stearic acid alcohol-based alcohol liquid is formed inside the forming tube 4, the sealing valve plate is opened. In this embodiment, the function of opening or closing the outlet end can be realized by driving the rotation of the sealing valve plate through a rotating motor. In addition, in this embodiment, the sealing valve plate can also be replaced with a detachable head, which is used for injection molding during the first start-up (it is not used frequently, so it can be directly disassembled manually) to prevent a large amount of material from flowing out; in addition, an exhaust hole can be opened on the surface of the head of the forming tube 4. The exhaust hole can ensure that the liquid can smoothly enter the forming tube 7.1 during injection molding, avoiding the problem of difficulty in injection molding due to increased pressure.

[0023] In addition, the present invention also discloses a molding method of the above-mentioned stearic acid alcohol-based solid alcohol automatic molding equipment, which comprises the following steps: S1, stearic acid alcohol-based alcohol liquid pipeline 1 feeds the feed pipeline 3 through the feed pump 2, controls the first solenoid valve 6 to open through the PLC controller 9, and then introduces the stearic acid alcohol-based alcohol liquid into the inlet of the first forming tube 4, at which time the blocking valve plate at the outlet end of the forming tube 4 is in a closed state; S2, when the first molding tube 4 is filled with stearic acid alcohol-based alcohol liquid, the PLC controller 9 closes the first solenoid valve 6, then opens the second solenoid valve 6, and introduces the stearic acid alcohol-based alcohol liquid into the inlet of the second molding tube 4, until the second molding tube 4 is filled with stearic acid alcohol-based alcohol liquid, then closes the second solenoid valve 6, and then opens the third solenoid valve 6, and repeats the process in sequence until all molding tubes 4 are filled with stearic acid alcohol-based alcohol liquid; S3, when the last molding tube 4 is filled with stearic acid alcohol-based alcohol liquid, the stearic acid alcohol-based alcohol liquid in the first molding tube 4 gradually solidifies and first solidifies into a solidified shape after the cooling process of the cooling water jacket 5, at this time the PLC controller 9 controls the first solenoid valve 6 to open, and opens the blocking valve plate at the outlet end of the first molding tube 4, after the stearic acid alcohol-based alcohol liquid is introduced into the inlet of the first molding tube 4, the stearic acid alcohol-based alcohol liquid pushes the stearic acid alcohol-based alcohol solid to move toward the outlet end of the first molding tube 4, after the photoelectric switch 8 at the outlet position of the first molding tube 4 detects that the stearic acid alcohol-based alcohol solid is discharged, the driving device of the slicer 7 drives the blade to slice the stearic acid alcohol-based alcohol solid; S4, when the stearic acid alcohol-based alcohol solid in the first molding tube 4 is almost completely pushed out, close the first solenoid valve 6, so that a part of the stearic acid alcohol-based alcohol solid is retained at the outlet position of the molding tube 4 as a blocking block to block the stearic acid alcohol-based alcohol liquid in the molding tube 4, waiting for the next cooling molding and slicing process; then the PLC controller 9 opens the second solenoid valve 6, and introduces the stearic acid alcohol-based solid alcohol liquid into the inlet of the second molding tube 4, and repeats the method in step S3, so that the stearic acid alcohol-based alcohol solid formed in the second molding tube 4 is subjected to the slicing process; after completing the slicing process of the stearic acid alcohol-based alcohol solid formed in the last molding tube 4, start the slicing process of the stearic acid alcohol-based alcohol solid formed in the first molding tube 4; S5. Repeat the above process continuously and periodically to achieve the continuous forming and slicing process of the stearic acid alcohol-based alcohol solid from the first forming tube 4 to the last forming tube 4.

[0024] Furthermore, in the step S1, before the first solenoid valve 6 is opened to introduce stearic acid alcohol-based alcohol liquid into the inlet of the first molding tube 4, the valves on the hot water inlet pipeline 5.3 and the hot water outlet pipeline 5.4 on the surface of all cooling water jackets 5 are opened in advance, and hot water is introduced into the cooling water jacket 5 to melt the stearic acid alcohol-based alcohol solids remaining in the molding tube 4 during the previous batch of production; then after the solenoid valve 6 is opened, the valves on the cooling water inlet pipeline 5.1 and the cooling water outlet pipeline 5.2 on the surface of all cooling water jackets 5 are opened to realize the cooling function of the cooling water jacket 5.

The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
