Description

Technical Field

[0001] This utility model relates to the field of candle production and forming equipment, and more particularly to an automatic filling and forming device for candles. Background Technology

[0002] Automatic candle filling and forming equipment is mainly used in candle manufacturing, especially in automated production processes, to pour molten wax into pre-set molds to form the shape of a candle. The main purpose of automatic candle filling and forming equipment is to improve the efficiency, quality and safety of candle production through automation technology and to meet the needs of large-scale production.

[0003] The main function of an automated candle-filling and molding device is to precisely pour molten wax into candle molds through an automated process, allowing it to cool and solidify naturally, thereby efficiently producing high-quality, consistent candles. The primary benefits of this automated device include improved production efficiency, ensured product quality, reduced production costs, and enhanced safety during the production process.

[0004] In the current candle production process, simple stirring alone is insufficient to ensure that the components of the wax are fully mixed. Candles made from unpressed wax have an inadequate internal structure. Candles with a loose texture are more susceptible to damage from collisions and vibrations during transportation and storage. Therefore, an automatic filling and forming device for candles is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automatic filling and forming device for candles, which aims to improve the problem that relying solely on simple stirring in the prior art makes it difficult to ensure that the components of the wax are fully blended.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic candle-forming device includes a wax barrel, a bidirectional lead screw rotatably connected to the bottom of the wax barrel, a rotating rod fixedly connected to the outside of the bidirectional lead screw, a bidirectional bearing threadedly connected to the top of the bidirectional lead screw, a cover plate fixedly connected to the outside of the bidirectional bearing, two limiting rods fixedly connected inside the wax barrel, the outer wall of the cover plate slidably connected to the outside of the limiting rods, a table rotatably connected to the outer wall of the bidirectional lead screw, and a transmission component provided at one end of the bidirectional lead screw.

The motor has a locking turntable fixedly connected to its drive end. The locking turntable has multiple locking slots on its outside for limiting the candle container.

[0012] As a further description of the above technical solution:

[0013] A conduit is fixedly connected to the bottom outer side of the wax oil barrel, and an injection head is fixedly connected to the side of the conduit away from the wax oil barrel;

[0014] As a further description of the above technical solution:

[0015] A fixing plate is fixedly connected to the top of the table, and a hydraulic rod is fixedly connected to the top of the fixing plate. The drive end of the hydraulic rod is fixedly connected to the top of the injection head.

[0016] As a further description of the above technical solution:

[0017] A conveyor belt is provided on the top of the table, and a candle wick bottle is fixedly connected to the top of the conveyor belt.

[0023] 1. In this utility model, the starting motor drives the first driving wheel to rotate, the first driving wheel drives the first belt and the first driven wheel to move together, the first driven wheel drives the double-sided lead screw to rotate, the double-sided lead screw rotates the rotating rod, thereby realizing the stirring of the candle oil. At the same time, the rotation of the double-sided lead screw drives the cover plate to move up and down, realizing the compression of the wax oil, ensuring that the internal structure of the candle is compact and the texture is uniform, enhancing the candle's resistance to collision and vibration during transportation and storage, and reducing the risk of damage.

[0024] 2. In this utility model, the starting motor drives the second driving wheel to rotate. The second driving wheel drives the second belt and the second driven wheel to move together.

[0032] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 3 and Figure 5 This utility model provides an embodiment of an automatic candle-forming filling device, comprising a wax tank 22, a bidirectional lead screw 9 rotatably connected to the bottom of the wax tank 22, a rotating rod 10 fixedly connected to the outside of the bidirectional lead screw 9, a bidirectional bearing 25 tightly connected to the top of the bidirectional lead screw 9 via threads, a cover plate 13 fixedly connected to the outer wall of the bidirectional bearing 25, a tension rod 12 rotatably connected to the outside of the wax tank 22, the other end of the tension rod 12 rotatably connected to the top of the cover plate 13, and the outer wall of the cover plate 13 slidably connected to the inner wall of the wax tank 22. Two limiting rods 11 are symmetrically fixed inside the wax tank 22. These two limiting rods 11 precisely limit the movement of the cover plate 13, allowing the outer wall of the cover plate 13 to slide smoothly and stably on the limiting rods 11, ensuring that it does not deviate or shake during lifting and lowering. A table 1 is rotatably connected to the outer wall of the bidirectional lead screw 9. A driven wheel 5 is fixedly connected to the side of the bidirectional lead screw 9 away from the wax oil tank 22. A motor 2 is fixed inside the table 1. The motor 2 serves as the power source for the entire device. Its drive end is firmly connected to the driving wheel 3. The driving wheel 3 and the driven wheel 5 are coupled externally through a belt 4. This connection method allows the rotational power of the motor 2 to be transmitted to the bidirectional lead screw 9, thereby realizing the automatic lifting and lowering of the cover plate 13. A conduit 14 is fixedly connected to the bottom outer side of the wax oil tank 22. An injection head 16 is fixedly connected to the side of the conduit 14 away from the wax oil tank 22. A fixing plate 23 is fixedly connected to the top of the table 1. A hydraulic rod 15 is fixedly connected to the top of the fixing plate 23. The drive end of the hydraulic rod 15 is fixedly connected to the top of the injection head 16. When the hydraulic rod 15 is activated, it can precisely control the operation of the injection head 16 and realize the precise injection of candle oil.

[0034] Reference Figure 1 , Figure 2 and Figure 4The motor 2 has a drive wheel 6 fixedly connected to its drive end to provide power to the system. The top of the table 1 is rotatably connected to a limiting turntable 19. A driven wheel 8 is fixedly connected to the outer wall of the limiting turntable 19. The drive wheel 6 and the driven wheel 8 are coupled together by a belt 7 to form a transmission component for power transmission. The driven wheel 8 can drive the limiting turntable 19 to rotate. The drive end of the motor 2 is not only fixedly connected to the drive wheel 6, but also fixedly connected to the positioning turntable 17. The positioning turntable 17 is used to precisely position the candle. A limiting rod 24 is slidably connected to the outside of the positioning turntable 17. The limiting rod 24 mainly controls the movement position of the candle. A conveyor belt 18 is fixedly connected to the bottom of the positioning turntable 17. Multiple candle wick bottles 20 are fixedly connected to the top of the conveyor belt 18. A second conveyor belt 21 is fixedly connected to the limiting rod 24.

[0035] Working principle: Wax oil is poured into wax oil tank 22 through the discharge port. Motor 2 is started, driving drive wheel 3, which in turn drives belt 4 and driven wheel 5 to rotate. Driven wheel 5 drives double-acting screw 9 to rotate, which in turn drives rotating rod 10 to rotate. Rotating rod 10 continuously agitates the wax oil in wax oil tank 22, ensuring uniform mixing and quality. The top of double-acting screw 9 is tightly connected to double-acting bearing 25 via threads. Double-acting bearing 25 is fixed to the inner side of cover plate 13. As double-acting screw 9 rotates, double-acting bearing 25 drives cover plate 13 to move smoothly up and down on double-acting screw 9, applying rhythmic pressure to the wax oil and further promoting its blending.

[0036] The candle container is placed on conveyor belt 18, which runs smoothly, carrying the candle container forward slowly. When the container moves below the wick bottle 20, the wick is precisely placed inside. At this time, motor 2 drives drive wheel 6 to rotate, which in turn drives belt 7 and driven wheel 8 to rotate. Driven wheel 8 drives limit turntable 19 to rotate. Limit turntable 19 has four locking positions, allowing only four candle containers to be conveyed to the locking turntable 17 each time it rotates, effectively preventing the locking turntable 17 from malfunctioning due to conveying too many containers at once. As the locking turntable 17 rotates, the candle containers are transported sequentially to below injection head 16. Hydraulic rod 15 is activated, pushing injection head 16 to precisely inject the well-stirred wax into the candle container. Subsequently, the candle container continues to rotate with the locking turntable 17. When it reaches the position of limit bar 24, it is blocked by limit bar 24 and pushed onto conveyor belt 21. Thus, a complete candle is made.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
