Description

Technical Field

[0001] This utility model belongs to the field of eyebrow pencil manufacturing technology, specifically relating to an eyebrow pencil refilling and ink filling mechanism. Background Technology

[0002] Eyebrow pencils generally consist of a barrel, a tip, and a refill. During production, pigments, oils, and waxes are mixed into an ink-like consistency and injected into the barrel containing the tip using an injection needle. This injection process can be divided into two types based on the way the barrel is positioned: vertical injection and horizontal injection. Each has its own characteristics. Vertical injection involves feeding the material vertically, often manually, which is inconvenient for batch processing. Therefore, manufacturers mostly use the horizontal injection method.

[0003] For horizontal core filling, a search revealed a Chinese utility model, CN212600097U, which describes a pressure filling device for eyebrow pencil cores. This device uses a rack and toothed belt for continuous feeding, and then activates a pressure cylinder to drive the piston to move laterally, pushing the core into the pencil barrel located on the rack and toothed belt.

[0004] During horizontal core injection, the pen barrel lies horizontally within the toothed space of the rack. Due to the difference between the teeth, it is difficult to align the pen barrel and the injection needle in a straight line. The two are prone to misalignment, which can cause the injection needle to rub against the pen barrel or even collide with it, thus hindering the continuity of horizontal core injection. Utility Model Content

[0005] The purpose of this invention is to provide an eyebrow pencil refill mechanism that can horizontally and vertically limit the pen barrel to quickly align with the injection needle, and uses friction to lock the pen barrel and counteract the impact of the refill.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] An eyebrow pencil refill mechanism includes a vertically arranged elastic element, a pressure head, a rack and pinion belt, a bracket, a V-shaped groove on the top of the bracket, and a lifting system connected to the bottom of the bracket. An injection needle is disposed outside the rack and pinion belt, a lateral movement system connected to the outside of the injection needle, and a pressurization system connected to the ink inlet of the injection needle. On an assembly line, the pencils, after being decapped, are placed one by one on top of the rack and pinion belt and transported intermittently in one direction until the pencil stops directly below the pressure head. The lifting system then... The pen barrel is supported by two V-shaped grooves, which horizontally limit its movement. The pressure head and the support vertically clamp the pen barrel, further limiting its movement. The horizontal movement system pushes the injection needle into the pen barrel opening, and the pressurization system draws in the ink-like mixture and injects it into the pen barrel under pressure. This facilitates rapid mixing. The friction between the pressure head and the support locks the pen barrel in place, thus counteracting the impact of the pressurized mixing.

[0008] As an alternative, a perforated silicone sheet is fixed to the bottom of the pressure head, and an alloy clamp and two elastic liners connected to both sides of the alloy clamp are fixed inside the V-shaped groove. One end of the elastic liner extends out of the V-shaped groove to rest on the top surface of the bracket.

[0009] As an alternative, one side of the rack belt is provided with a first flange and a suspension plate connected to the first flange, the suspension plate being connected to an elastic element, and the other side of the rack belt is provided with a second flange and a guide hole located at the top of the second flange.

[0010] As an alternative, the elastic element includes a vertically arranged alloy cylinder, a perforated flange plate connected to the opening of the alloy cylinder, a first slide rod, and a spring surrounding the first slide rod, wherein one end of the first slide rod is fixedly connected to the top of the pressure head, and the other end is inserted into the alloy cylinder.

[0011] As an optional solution, the lifting system includes a concave seat arranged vertically in sequence and a vertical cylinder connected to the bottom of the concave seat. The two sides of the top of the concave seat are respectively fixedly connected to the bottom of the two brackets. When the vertical cylinder is activated, the two brackets can be moved vertically at the same time until they are higher than the rack belt to lift the pen barrel. The pen barrel is then clamped vertically by the pressure head. After the core is injected, the pen barrel is put back into the rack belt by lowering the two brackets, which facilitates the continuous loading and unloading of the core injection action.

[0012] As an alternative, the lateral movement system includes a hollow second slide bar, a perforated slide block penetrated by the second slide bar, and a transverse cylinder connected to the tail of the second slide bar. The injection needle inlet is connected to a pressurization system via the second slide bar.

[0013] As an alternative, the pressurization system includes a liquid pump disposed outside the rack belt and a transfer tank connected to the liquid pump, the outlet of the transfer tank being connected to the head of the second slide bar.

[0014] The technical effects achieved by this utility model are as follows:

[0015] In this invention, on an assembly line, pen barrels after being decapped are placed one by one on top of a rack belt and transported intermittently in one direction until they stop directly below the pressure head. The lifting system then uses a jogging motion to lift the bracket, with two V-shaped grooves supporting both ends of the pen barrel. This horizontal restraint of the pen barrel by the V-shaped grooves, combined with the vertical restraint of the pen barrel by the pressure head and bracket, ensures rapid alignment with the injection needle. Furthermore, a lateral movement system pushes the needle tip into the pen barrel opening, and a pressurization system draws in ink-like mixture, pressurizing it along the injection needle and injecting it into the pen barrel. This facilitates rapid mixing and ensures the pen barrel is locked in place by friction between the pressure head and bracket, thus counteracting the impact of the pressurized mixing.

[0016] This invention uses a perforated silicone sheet and two elastic liners to wrap the pen barrel. The deformation of both can cushion the pen barrel and prevent excessive compression. After clamping, the arc surface of the alloy clamp is used to fit against the outer arc surface of the pen barrel, so as to accurately position and align with the injection needle to prevent misalignment.

[0026] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0027] like Figures 1-7As shown, an eyebrow pencil refilling mechanism can be controlled by an industrial computer, using an RS485 bus to transmit control signals. For horizontal refilling, this embodiment includes a vertically arranged elastic element, a pressure head 1, a rack belt 2, a bracket 3, a V-shaped groove 4 on the top of the bracket 3, and a lifting system connected to the bottom of the bracket 3. On the production line, a servo motor on the workbench drives a sprocket to rotate the annular rack belt 2, placing the decapped pencils one by one onto the top of the rack belt 2. This is done intermittently in a one-way direction until the pencil stops directly below the pressure head 1. The lifting system then jogs the bracket 3, allowing the two V-shaped grooves 4 to support the ends of the pencil, thus subjecting the pencil to V-shaped grooves. The horizontal limiting effect of the groove 4, coupled with the vertical clamping of the pen barrel by the pressure head 1 and the bracket 3, further limits the vertical positioning of the pen barrel, allowing for quick alignment with the injection needle 5. Moreover, the injection needle 5 is externally mounted on the rack belt 2, and a transverse moving system connected to the outside of the injection needle 5, along with a pressurizing system connected to the liquid inlet of the injection needle 5, pushes the needle tip of the injection needle 5 into the pen barrel opening via the transverse moving system. The pressurizing system draws in the ink-like mixture and pressurizes it along the injection needle 5, injecting it into the pen barrel for quick and easy mixing. The injection volume is controlled by setting the pressurization time on the industrial computer. Furthermore, the friction between the pressure head 1 and the bracket 3 locks the pen barrel, thus counteracting the impact of the pressurized mixing.

[0028] See attached document Figure 1 , Figure 2 and Figure 3 The lifting system of this embodiment includes a concave seat 13 arranged vertically in sequence and a vertical cylinder 12 connected to the bottom of the concave seat 13 by bolts. The vertical cylinder 12 is installed on the worktable below the pressure head 1 by bolts and is connected to the industrial computer by relay signal for control signal transmission. Since the two sides of the top of the concave seat 13 are fixedly connected to the bottom of the two brackets 3 by bolts, when the air pump a is started to drive the vertical cylinder 12, the two brackets 3 can be moved vertically at the same time until they are higher than the rack belt 2 to lift the pen barrel and cooperate with the pressure head 1 to vertically clamp the pen barrel. After the core is injected, the pen barrel is put back into the rack belt 2 by lowering the two brackets 3, which facilitates the continuous loading and unloading of the core injection action.

[0029] See attached document Figure 3 , Figure 4 and Figure 6To avoid damaging the pen barrel, this embodiment has a perforated silicone sheet 101 bonded to the bottom of the pressure head 1, and an alloy clamp 401 and two elastic inner liners 402 connected to both sides of the alloy clamp 401 bonded inside the V-groove 4. The pen barrel is wrapped by the perforated silicone sheet 101 and the two elastic inner liners 402. The deformation of the two can buffer the pen barrel and prevent excessive compression. After clamping, the arc surface of the alloy clamp 401 is used to adhere to the outer arc surface of the pen barrel, and it is accurately positioned to align with the injection needle 5 to prevent misalignment. One end of the elastic inner liner 402 extends out of the V-groove 4 to rest on the top surface of the bracket 3, so that it can approach the pen barrel in a wide-angle posture and guide the pen barrel to be close to the alloy clamp 401.

[0030] See attached document Figure 2 , Figure 5 and Figure 6 The rack belt 2 has a first flange 6 and a suspension plate 601 connected to the first flange 6 on one side. The suspension plate 601 is connected to the elastic member to keep the elastic member in a vertical state. The rack belt 2 has a second flange 7 and a guide hole 701 at the top of the second flange 7 on the other side. When the injection needle 5 is pushed, it passes through the guide hole 701, so that the second flange 7 can protect the injection needle 5 from the outside.

[0031] See attached document Figure 5 and Figure 6 The elastic element includes a vertically arranged alloy cylinder 8, a perforated flange plate 9 connected to the opening of the alloy cylinder 8, a first slide rod 10, and a spring 11 surrounding the first slide rod 10. One end of the first slide rod 10 is welded to the top of the pressure head 1, and the other end is inserted into the alloy cylinder 8. The two ends of the spring 11 are welded to the top of the pressure head 1 and the bottom surface of the perforated flange plate 9, respectively. When the pen barrel presses against the pressure head 1, the spring 11 is compressed on one side, and the first slide rod 10 is pushed to slide up along the round hole of the perforated flange plate 9 on the other side, leaving a safe distance until the lifting system stops. When the core injection is completed, the pen barrel descends and disengages from the pressure head 1. As the spring 11 recovers its deformation, it pulls the first slide rod 10 down and drives the pressure head 1 to reset.

[0032] See attached document Figure 1 , Figure 2 and Figure 7 The transverse system of this embodiment includes a hollow second slide rod 15, a perforated slide block 14 through which the second slide rod 15 passes, and a transverse cylinder 16 connected to the tail of the second slide rod 15. The transverse cylinder 16 is connected to an industrial computer, and the air pump b is started to drive the cylinder rod of the transverse cylinder 16, pushing the second slide rod 15 to extend along the round hole of the perforated slide block 14 until the injection needle 5 is inserted into the pen barrel. Since the liquid inlet of the injection needle 5 is connected to the pressurization system through the second slide rod 15, the pressurization system can be started to draw in the ink-like mixture and inject it into the pen barrel under pressure. After a certain period of time, a certain amount of mixture is injected, and then the second slide rod 15 is pulled back to make the injection needle 5 detach from the pen barrel.

[0033] See attached document Figure 1 , Figure 2 and Figure 7 The pressurization system includes a liquid pump 17 located outside the rack belt 2 and a transfer tank 18 connected to the liquid pump 17. The liquid pump 17 is connected to an industrial computer via a relay. The liquid pump 17 is started to draw ink-like mixture from the material cylinder. Since the outlet of the transfer tank 18 is connected to the head of the second slide bar 15 via a hose, the mixture is sent to the injection needle 5 via the transfer tank 18, the hose and the second slide bar 15. After a certain period of time, the liquid pump 17 is stopped.

[0034] The working principle of this utility model is as follows: During operation, on the assembly line, the servo motor drives the sprocket to rotate the annular rack belt 2, and the pen barrels after the caps are removed are placed one by one on the top of the rack belt 2 for unidirectional intermittent transport until the pen barrel stops directly below the pressure head 1. The lifting system then lifts the bracket 3 in a jogging manner, and the two ends of the pen barrel are supported by two V-shaped grooves 4 respectively, so that the pen barrel is subject to the horizontal limiting effect of the V-shaped grooves 4. In addition, the pressure head 1 and the bracket 3 vertically clamp the pen barrel, which also subjectes the pen barrel to a vertical limiting effect, so as to quickly align the needle tip of the injection needle 5.

[0035] Then, the needle of the injection needle 5 is pushed by the transverse system to insert into the opening of the pen barrel. The pressurization system draws the ink-like mixture along the injection needle 5 and injects it into the pen barrel under pressure, which facilitates the rapid mixing of the material. The amount of core injected is controlled by setting the pressurization time on the industrial computer. Moreover, the pen barrel is locked by the friction between the pressure head 1 and the bracket 3, thereby counteracting the impact of the pressurized mixing.

[0036] The above description is merely an optional embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional methods in the field.
