Description

Technical Field

[0001] This utility model relates to the field of plant wax production technology, and in particular to an anti-clogging valve used in plant wax production. Background Technology

[0002] Plant waxes are key components in cosmetics such as lipsticks, thanks to their low melting points (25°, 28°, and 40°) and their ability to improve product diffusion. However, in the industrial production of plant waxes, if the production process is paused after the liquid product flows through the valve, the residual wax will solidify rapidly due to cooling, easily causing blockage inside the valve and becoming a technical bottleneck affecting production continuity.

[0003] A search revealed that patent CN203335902U discloses a self-dissolving anti-clogging valve used in the production of plant wax. The valve has heating devices on both the feed cylinder and the sleeve, which can melt the solidified plant wax and thus prevent the valve from clogging.

[0004] However, the above-mentioned device has the following drawbacks: First, although electric heating is provided, whether the heat can be effectively and timely transferred to the threaded parts (especially the internal threads at the end cap) is a problem. This part is located at the top of the valve and is a heat blind spot, making it most susceptible to cooling. If plant wax penetrates the threaded part, it is prone to jamming once it cools down. Second, the externally wound heating wire may cause the sleeve wall to overheat while the temperature of the central material is insufficient, resulting in low heating efficiency. The threaded transmission part is not effectively heated, which remains a weak point. Therefore, further improvements are needed. To this end, we have proposed an anti-clogging valve for plant wax production. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an anti-clogging valve for the production of plant waxes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an anti-clogging valve for plant wax production, comprising a valve tube with both ends open, one end of the valve tube being a feed inlet, a discharge pipe fixedly installed on the side wall of the valve tube, a piston slidably disposed inside the valve tube, a drive assembly for driving the piston to move being installed at the end of the valve tube away from the feed inlet, a jacket being fixedly sleeved on the outer walls of the valve tube and the discharge pipe, and an electric heating wire being disposed inside the jacket, the jacket being filled with heat-conducting oil, and a maintenance pipe being fixedly disposed on the side wall of the valve tube facing the discharge pipe.

[0007] Furthermore, annular grooves are provided at both ends of the outer wall of the piston, and a sealing ring is engaged inside each annular groove.

[0008] Furthermore, the piston has a threaded groove and a through groove at one end near the drive assembly. The drive assembly includes an end plate fixedly connected to the valve tube. A servo motor is fixed to the surface of the end plate. A lead screw is fixed to the output end of the servo motor. The lead screw passes through the threaded groove and is threadedly connected to the threaded groove. A guide rod is fixed to the side of the end plate located inside the valve tube. The guide rod passes through the through groove and is slidably connected to the through groove.

[0009] Furthermore, a housing is fixedly connected to the side of the end plate outside the valve tube, and a controller is installed inside the housing. A remote control terminal is provided to match the controller, and the servo motor is electrically connected to the controller.

[0010] Furthermore, a temperature sensor is installed inside the jacket, and both the temperature sensor and the electric heating wire are electrically connected to the controller.

[0011] Furthermore, an inspection cover is fixedly connected to the end of the inspection pipe away from the valve pipe.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-3 As shown, this relates to an anti-clogging valve in the production of plant wax, including a valve tube 1, both ends of which are open. One end of the valve tube 1 is a feed inlet 2, and a discharge pipe 3 is fixedly installed on the side wall of the valve tube 1. A piston 4 is slidably installed inside the valve tube 1. A drive assembly 5 for driving the piston 4 is installed at the end of the valve tube 1 away from the feed inlet 2. A jacket 6 is fixedly sleeved on the outer side walls of the valve tube 1 and the discharge pipe 3. An electric heating wire 7 is installed inside the jacket 6, and the jacket 6 is filled with heat-conducting oil. A maintenance pipe 9 is fixed on the side wall of the valve tube 1 facing the discharge pipe 3.

[0023] Both ends of the outer wall of piston 4 are provided with annular grooves, and a sealing ring 43 is engaged inside each annular groove.

[0024] In this embodiment, the sealing ring 43 is made of high temperature resistant material, and the sealing ring 43 is tightly fitted to the inner wall of the valve tube 1, so that the sealing ring 43 achieves the seal between the piston 4 and the inner wall of the valve tube 1.

[0025] The piston 4 has a threaded groove 41 and a through groove 42 at one end near the drive assembly 5. The drive assembly 5 includes an end plate 51 fixedly connected to the valve tube 1. A servo motor 52 is fixed on the surface of the end plate 51. A lead screw 53 is fixed at the output end of the servo motor 52. The lead screw 53 passes through the threaded groove 41 and is threadedly connected to the threaded groove 41. A guide rod 54 is fixed on the surface of the end plate 51 located inside the valve tube 1. The guide rod 54 passes through the through groove 42 and is slidably connected to the through groove 42.

[0026] Guided by the guide rod 54 and the through groove 42, after the servo motor 52 is started, the servo motor 52 drives the lead screw 53 to rotate. The lead screw 53 drives the piston 4 to slide along the guide rod 54, thereby enabling the piston 4 to move inside the valve tube 1. By controlling the forward or reverse rotation of the servo motor 52, the piston 4 can reciprocate inside the valve tube 1. When the piston 4 moves to block the discharge pipe 3, the valve is closed; when the piston 4 moves away from the discharge pipe 3, the valve is opened.

[0027] The end plate 51 is fixedly connected to the outer shell 55 on one side outside the valve pipe 1. The controller 56 is installed inside the outer shell 55. A remote control terminal is provided to match the controller 56. The servo motor 52 is electrically connected to the controller 56.

[0028] In this embodiment, a remote transmission module is also provided inside the outer casing 55, which can be a 5G module. The controller 56 is a PLC controller, specifically a Siemens SIMATIC S7-1500 CPU 1516-3PN / DP. The remote control terminal is a mobile phone control program. After the open / close command is input through the remote control terminal, it is transmitted to the controller 56 through the remote transmission module. The controller 56 controls the servo motor 52 to rotate forward or reverse, thereby realizing the opening or closing of the valve.

[0029] A temperature sensor 8 is installed inside the jacket 6. Both the temperature sensor 8 and the electric heating wire 7 are electrically connected to the controller 56.

[0030] In this embodiment, the temperature sensor 8 is an NTC thermistor (such as the MF52 series). The temperature sensor 8 monitors the oil temperature inside the jacket 6 in real time and feeds the temperature information back to the controller 56. When the temperature is below the preset lower limit of the controller 56, the controller 56 activates the electric heating wire 7 to heat the heat transfer oil, which in turn indirectly heats the plant wax inside the valve tube 1. Since the heat transfer oil completely surrounds the valve tube 1, uniform and rapid heating is achieved. When the temperature sensor 8 detects a temperature higher than the preset upper limit of the controller 56, the controller 56 stops the electric heating wire 7 from operating.

[0031] An inspection cover 10 is fixedly connected to the end of the inspection pipe 9 away from the valve pipe 1. This allows for emergency maintenance of the valve pipe 1 by removing the inspection cover 10.

[0032] Working principle: When the valve needs to be opened, the controller 56 drives the servo motor 52 to rotate forward according to the instruction issued by the remote control terminal. The servo motor 52 drives the lead screw 53 to rotate. Under the guidance and constraint of the guide rod 54 and the through groove 42, the piston 4 moves along the valve pipe 1 away from the discharge pipe 3, thereby opening the flow path and allowing the material to enter from the inlet 2 and be discharged through the discharge pipe 3. When the valve needs to be closed, the controller 56 controls the servo motor 52 to reverse, driving the piston 4 to move closer to the discharge pipe 3 until the discharge pipe 3 is blocked. At the same time, the residual material in the valve pipe 1 is pushed back to achieve a tight closure.

[0033] Whether the valve is opened or closed, the controller 56 first controls the electric heating wire 7 to start heating the heat transfer oil. The jacket 6 provides uniform heat preservation for the valve tube 1 and the discharge tube 3 to prevent the plant wax from solidifying. Throughout the operation, the temperature sensor 8 monitors the temperature of the heat transfer oil in the jacket 6 in real time and feeds it back to the controller 56. If the temperature is lower than the set lower limit, the controller 56 starts the electric heating wire 7 to heat the heat transfer oil. The jacket 6 provides uniform heat preservation for the valve tube 1 and the discharge tube 3 to prevent the plant wax from solidifying. If the temperature exceeds the set upper limit, heating stops, thus ensuring that the valve always operates stably at a suitable temperature.
