Description

Technical Field

[0001] This invention relates to the field of cosmetic filling and production technology, specifically to an automated production process for pen-type cosmetics. Background Technology

[0002] The manufacturing process of pen-type cosmetics, including filling, cooling and molding, core cutting and alignment, assembly, and final assembly, generally employs an assembly line production process. It is difficult to achieve full automation across all processes. On the one hand, this requires a high degree of human involvement; on the other hand, the transitions between different processes can lead to a decrease in product quality and an increase in the defect rate.

[0003] For example, referring to the patent application for an automatic eyebrow pencil lead cutting device (publication number: CN221818782U), during the process of cutting and collecting the lead, the stress and hardness of the lead can lead to an increase in the defect rate and a decrease in quality. Moreover, the lead needs to be exposed to the external environment for a long time, which places high demands on the production environment.

[0004] To address this, we propose a novel automated production process for pen-based cosmetics to achieve fully automated production of pen-type cosmetics. Summary of the Invention

[0005] The technical problem solved by this invention is to provide a fully automated production process for pen-type cosmetics.

[0006] The technical solution adopted by this invention to solve its technical problem is: An automated production process for pen-type cosmetics includes the following steps: S1: Automatic oiling. The pen refill mold is conveyed to the oiling station. The oiling module drips a certain amount of oil into the pen refill forming cavity of the pen refill mold through the oiling needle nozzle. The first cylinder drives the ejector pin in the pen refill forming cavity to move up and down, so as to spread the oil droplets in the pen refill forming cavity evenly. S2: Automatic oil suction. After the pen refill mold has dripped oil, it is conveyed to the oil suction station. The oil suction module drives the ejector pin in the pen refill forming mold cavity to rise through the second cylinder, pushing out and sucking away the excess oil droplets in the pen refill forming mold cavity. S3: Automatic uniform speed filling: After the ink is absorbed, the pen refill mold is conveyed to the filling station. The filling module injects a fixed amount of pen refill material into the pen refill forming mold cavity at a uniform speed through the filling needle. S4: Step-by-step cooling and solidification molding. The pen refill mold filled with pen refill material is conveyed to the cooling station. The pen refill material in the pen refill mold is subjected to step-by-step cooling and solidification molding by low-temperature fluid to form a pen refill. S5: Automatic core cutting and alignment: After cooling and forming, the pen refill mold is conveyed to the automatic core cutting and alignment station. The automatic core cutting module drives the ejector pin to rise through the third cylinder, pushing the cooled and formed pen refill out of the pen refill forming cavity a preset distance, so that the pen refill protrudes from the pen refill mold. The automatic core cutting module then cuts off the exposed pen refill with a blade, thus realizing the automatic core cutting and alignment of the pen refill. S6: Automatic Demolding and Assembly: The pen refill mold after core cutting and alignment is conveyed to the automatic demolding station. The automatic demolding module drives the ejector pin to rise through the fourth cylinder, pushing the core cut and aligned pen refill into the pen barrel, thus completing the automatic demolding and assembly of the pen refill.

[0007] Furthermore, in step S2, the oil suction module uses high-pressure gas to disperse the oil droplets and then uses an oil suction device to remove the dispersed oil mist.

[0008] Furthermore, the oil-absorbing module includes an oil-absorbing cylinder and several air nozzles regularly arranged in the oil-absorbing cylinder. The oil-absorbing cylinder is driven by a cylinder to descend and fit against the mold opening at the upper end of the pen refill mold. The mold opening passes through the lower end of the oil-absorbing cylinder and extends into the inner cavity of the oil-absorbing cylinder. The several air nozzles are aligned with the mold opening, and high-pressure gas is blown towards the mold opening through the pipeline and the several air nozzles, blowing the pushed-out oil droplets into the inner cavity of the oil-absorbing cylinder. The oil-absorbing module also includes an oil-absorbing device, which draws air from the inner cavity of the oil-absorbing cylinder through the oil-absorbing pipeline to remove the oil mist blown into the inner cavity of the oil-absorbing cylinder.

[0009] Furthermore, in step S3, the filling module is driven to rise and fall at a constant speed by a power device, and a push rod is driven by another power device to push the pen refill material in the filling valve body at a constant speed, thereby achieving uniform upward filling.

[0010] Furthermore, in step S4, the cooling station is located behind the filling station, occupying at least three stations; the low-temperature fluid flows in from the last station of the cooling station and flows forward sequentially to cool the pen refill mold; the low-temperature fluid undergoes heat exchange sequentially from the first station to the last station of the cooling station, and the temperature decreases, forming a stepped cooling system.

[0011] Furthermore, in step S5, a waste collection module is regularly installed at the automatic core-cutting and alignment station. The waste collection module uses a suction tube to quickly suck away the remaining remnants of the cut core.

[0012] Furthermore, in step S6, the automatic demolding module includes a pen barrel fixture for loading the pen barrel. The pen barrel fixture is fitted onto the mold opening at the upper end of the pen refill mold, and a pressure plate is driven down by a cylinder to press and fix the pen barrel to the upper end of the pen barrel fixture.

[0013] Furthermore, in steps S1-S3, the pen refill mold is continuously heated and kept warm by a high-temperature fluid.

[0014] Furthermore, after the filling process is completed, the high-temperature fluid used to heat and keep the pen refill mold warm is blown away and discharged by high-pressure gas; after the pen refill cools and solidifies, the low-temperature fluid used to cool the pen refill mold is also blown away and discharged by high-pressure gas.

[0015] Furthermore, the oil-drip module, oil-absorption module, filling module, automatic core-cutting module, and automatic demolding module are arranged regularly around the turntable module and installed in the machine in a regular manner along with the turntable module, forming a turntable-type automatic filling production equipment for pen cosmetics and its production process.

[0016] The beneficial effects of this invention are: The automated production process for pen-type cosmetics of this invention integrates automatic oiling, automatic oil suction, automatic uniform-speed filling, automatic core cutting and alignment, automatic waste collection, and automatic demolding and assembly. This achieves automated oiling and suction of the pen core mold, automated uniform-speed filling of the pen core material, and automated core cutting and alignment, waste collection, and demolding and assembly of the pen core. Thus, automated filling and production of pen-type cosmetics can be completed in a single machine without manual intervention, greatly improving production efficiency and product quality while reducing production costs and defect rates.

[0018] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0020] like Figures 1-4 As shown, the present invention provides an automated production process for pen-type cosmetics, including the following steps: S1: Automatic oiling. The pen refill mold 9 is conveyed to the oil dripping station. The oil dripping module 3 drips a certain amount of oil into the pen refill forming cavity of the pen refill mold 9 through the oil dripping needle nozzle. The ejector pin in the pen refill forming cavity is driven up and down by a power device such as a cylinder to spread the oil droplets in the pen refill forming cavity evenly.

[0021] In one embodiment, such as Figure 3 and Figure 4 As shown, the pen refill mold 9 includes a mold base 91 and a plurality of pen refill forming molds 92 disposed in the mold base 91. The pen refill forming cavity 9201 is vertically disposed in the pen refill forming mold 92, and its shape and inner diameter are not limited. The ejector pin 93 extends into the pen refill forming cavity 9201 from below and is fitted against the inner wall. It is driven by a power device such as a cylinder to move up and down in the pen refill forming cavity 9201.

[0022] S2: Automatic oil suction. After the pen refill mold 9 is dripped with oil, it is conveyed to the oil suction station. The oil suction module 4 drives the ejector pin under the pen refill mold 9 to rise through a power device such as a cylinder, pushing out and sucking away the excess oil droplets in the pen refill forming cavity.

[0023] The oil suction module 4 includes an oil suction device, an oil suction cylinder, and a cylinder that drives the oil suction cylinder to move up and down. The oil suction cylinder is located above the pen refill mold 9, and its lower end is provided with a slot that fits with the mold opening 9101 at the upper end of the pen refill mold 9. The mold opening at the upper end of the pen refill mold passes through the slot at the lower end of the oil suction cylinder and extends into the inner cavity of the oil suction cylinder.

[0024] Furthermore, the oil suction module 4 uses a cylinder to drive the ejector pin to push out excess oil droplets from the pen refill forming mold cavity, and uses high-pressure gas to blow away the pushed-out oil droplets. At the same time, the oil suction device sucks away the blown-away oil mist.

[0025] Furthermore, the oil suction cylinder is regularly equipped with several air nozzles for supplying compressed air. These nozzles extend into the inner cavity of the oil suction cylinder and are aimed at the mold opening on the pen refill mold 9. Air is blown onto the mold opening, dispersing the oil droplets pushed out of the mold opening into the inner cavity of the oil suction cylinder. Simultaneously, the oil suction device is connected to the inner cavity of the oil suction cylinder through an oil suction pipe. The oil suction device draws air from the inner cavity of the oil suction cylinder through the oil suction pipe, sucking away the oil mist blown into the inner cavity of the oil suction cylinder.

[0026] Furthermore, the oil suction module 4 uses a cylinder to drive the ejector pin upwards, pushing out excess oil droplets from the pen refill molding cavity. Then, compressed air is activated, blowing air through several nozzles into the mold opening, dispersing the pushed-out oil droplets into the inner cavity of the oil suction cylinder. Simultaneously, the oil suction device (vacuum device or dust collector) is activated, sucking away the oil mist blown into the inner cavity of the oil suction cylinder.

[0027] S3: Automatic uniform speed filling. After the ink-absorbing pen refill mold 9 is conveyed to the filling station, the filling module 3 uniformly fills a certain amount of pen refill material into a number of pen refill forming cavities through a number of filling needles.

[0028] Furthermore, the filling module 3 includes a filling valve body, a three-way valve core and its power unit, a push rod and its power unit, a material tank, and a lifting platform. The filling valve body includes a valve cavity and several sets of feed channels, material chambers, and discharge channels regularly arranged at the upper, rear, and lower ends of the valve cavity. The material tank is fixedly installed at the upper end of the filling valve body and is connected to the feed channel of the filling valve body via a feeding pipeline. The three-way valve core is fitted into the valve cavity and is rotatably installed within the valve cavity of the filling valve body via its power unit. The push rod is located in the material chamber at the rear end of the filling valve body and is driven by its power unit to move back and forth within the material chamber. Filling needles for filling are regularly arranged in the discharge channel at the lower end of the filling valve body.

[0029] Furthermore, the three-way valve core has T-shaped holes regularly arranged at several sets of inlet channels, material chambers, and outlet channels, connecting them in pairs. The three-way valve core is driven by its power device to rotate within the valve chamber, sequentially connecting the inlet channel with the material chamber, and the material chamber with the outlet channel. When the three-way valve core is driven by the power device to connect the inlet channel and the material chamber, the material barrel conveys the pen refill material to be filled into the material chamber through the feeding pipe and the inlet channel. When the three-way valve core is driven by the power device to connect the material chamber and the outlet channel, the push rod behind the material chamber is driven by the power device to push the pen refill material in the material chamber out of the outlet channel and the filling needle for filling.

[0030] Furthermore, the power unit of the push rod drives the push rod forward at a constant speed through the lead screw, thereby achieving uniform filling.

[0031] Furthermore, the material hopper, the three-way valve core and its power unit, the push rod and its power unit are installed and fixed together with the filling valve body on the lifting platform. The lifting platform is driven to rise and fall at a constant speed by the lifting motor and the lifting screw, thereby driving the filling needle to rise and fall at a constant speed.

[0032] The filling module performs the following actions: First, the three-way valve core power unit drives the three-way valve core to rotate, opening the feed channel and the material chamber, and closing the discharge channel. The pen refill material in the material tank flows into the material chamber of the filling valve body. Then, the lifting platform drives the filling needle to descend and extend into the bottom of the pen refill forming cavity of the pen refill mold. Next, the three-way valve core power unit drives the three-way valve core to rotate, opening the material chamber and the discharge channel, and closing the feed channel. Then, the push rod, driven by its power unit and lead screw, pushes forward at a uniform speed, pushing the pen refill material in the material chamber out of the filling needle at a uniform speed for uniform filling. Simultaneously, the lifting platform, driven by the lifting motor and lifting lead screw, rises at a uniform speed, thereby achieving uniform upward filling of the filling needle to further improve product quality.

[0033] Furthermore, a heat-insulating plate is regularly installed next to the filling nozzle. The heat-insulating plate is positioned close to the filling nozzle and is driven by a cylinder to move closer to and away from the filling nozzle. During the filling process, the heat-insulating plate is driven by the cylinder to move away from the filling nozzle; after the filling process is completed, the heat-insulating plate is driven by the cylinder to move closer to the filling nozzle to heat and insulate it, so as to prevent the residual pen refill material in the filling nozzle from pre-cooling and solidifying, causing blockage of the filling nozzle and affecting subsequent filling operations.

[0034] During filling, in order to prevent the temperature in the pen refill molding cavity from being too low and the pen refill material from suddenly solidifying upon contact with cold, thus causing product defects, the pen refill mold 9 needs to be continuously heated and kept warm in steps S1-S3.

[0035] S4: Step-by-step cooling and solidification molding. The pen refill mold 9, filled with pen refill material, is conveyed to the cooling station. The pen refill material in the pen refill mold is cooled and solidified in a step-by-step manner by low-temperature fluid to form a pen refill.

[0036] The cooling station is located after the filling station, occupying at least three stations. The cryogenic fluid flows in from the last station of the cooling station and then flows forward sequentially to cool the pen refill mold. The cryogenic fluid undergoes heat exchange sequentially from the first station to the last in the cooling station, with the temperature decreasing progressively. Therefore, a "tiered cooling" system is formed at the cooling station. This prevents the filling material from cooling abruptly after filling, which could cause product defects and reduce product quality.

[0037] Furthermore, in one embodiment, after filling, the high-temperature fluid used to heat and maintain the temperature of the pen refill mold is blown away and discharged by high-pressure gas. Correspondingly, after cooling, the low-temperature fluid used to cool the pen refill mold is blown away and discharged by high-pressure gas.

[0038] S5: Automatic Core Cutting and Alignment: After cooling and forming, the pen refill mold is conveyed to the automatic core cutting and alignment station. The automatic core cutting module uses a power device such as an air cylinder to drive the ejector pin to rise, pushing the cooled pen refill out of the pen refill forming cavity a preset distance, so that the pen refill protrudes from the pen refill mold. Subsequently, the automatic core cutting module uses a sharp blade to cut off the exposed pen refill, realizing the automatic core cutting and alignment of the pen refill.

[0039] Furthermore, the automatic core-cutting module includes a blade fixedly mounted above the core mold. After the core is ejected and exposed, it is quickly cut off by the blade when it is conveyed to the blade, so as to ensure that the length of several formed cores remains consistent.

[0040] Furthermore, to collect the cut pen refill material, a waste collection module is installed next to the blade. This module includes a suction device and an air hose, with the air hose's tip positioned close to the blade via a bracket. When the exposed pen refill is cut, the vacuum cleaner quickly sucks away the remaining refill material through the air hose.

[0041] S6: Automatic Demolding and Assembly: The pen refill mold after core cutting and alignment is conveyed to the automatic demolding station. The automatic demolding module drives the ejector pin to rise through the cylinder, pushing the core cut and aligned pen refill into the pen barrel, thus completing the demolding and assembly of the pen refill.

[0042] Furthermore, in the automatic demolding and assembly process, a pen barrel mounting fixture needs to be fixed on the mold opening at the upper end of the pen refill mold 9. The upper end of the pen barrel fixture, at the position of the pen refill forming mold cavity, has regularly arranged pen barrel slots for mounting the pen barrel and pen refill through holes for easy pen refill passage. The pen barrel is inserted into the pen barrel slot with the head facing down, so that the pen refill mounting hole at the pen barrel head is aligned with the pen refill through hole and the pen refill forming mold cavity.

[0043] Furthermore, a pressure plate and a pressure plate cylinder are fixedly mounted on the upper part of the pen barrel fixture via a bracket. The pressure plate cylinder drives the pressure plate to move up and down above the pen barrel fixture. When the pen barrel is inserted into the upper end of the pen barrel fixture, the pressure plate cylinder drives the pressure plate to press down, pressing the pen barrel firmly and fixing it to the upper end of the pen barrel fixture. Then, the cylinder drives the ejector pin to push the pen refill into the pen refill mounting hole at the head of the pen barrel, completing the automatic demolding and assembly of the pen refill. Subsequently, the pen barrel containing the pen refill is removed from the pen barrel fixture, the cap is closed, and the automatic filling and assembly of pen-type cosmetics is completed.

[0044] like Figure 2As shown, the oil dripping module 3, oil absorption module 4, filling module 5, automatic core cutting module 6, waste collection module 7, and automatic demolding module 8 are arranged regularly around the turntable module 2 and installed in the machine base 1 in a regular manner along with the turntable module 2, forming a turntable-type automatic filling production equipment for pen cosmetics.

[0045] The turntable module 2, along with the oil dripping module 3, oil suction module 4, filling module 5, automatic core cutting module 6, waste collection module 7, and automatic demolding module 8, sequentially forms an oil dripping station, an oil suction station, a filling station, a cooling station, an automatic core cutting and waste collection station, and an automatic demolding station. The cooling station is located between the filling station and the automatic core cutting and waste collection station. The automatic core cutting module 6 and the waste collection module 7 share a single station, forming the automatic core cutting and waste collection station.

[0046] Furthermore, the process flow of the rotary automatic filling production equipment for pen-type cosmetics is as follows: Driven by a motor, the turntable module 2 rotates several pen refill molds 9 sequentially at the lower ends of the oil-drip module 3, oil-absorption module 4, filling module 5, core-cutting module 6, waste collection module 7, and demolding module 8. The pen refill molds 9 sequentially undergo oil dripping and film formation at the oil-drip station, oil absorption at the oil-absorption station, filling at the filling station, cooling and shaping at the cooling station, core-cutting alignment and waste collection at the automatic core-cutting and waste collection stations, and demolding and assembly at the demolding station, thus realizing the automatic filling and production of pen-type cosmetics in one machine.

[0047] Furthermore, the turntable module 2 has several turntable cavities arranged in a circular array, and several pen refill molds 9 are regularly installed in these cavities. High-temperature fluid flows sequentially through the turntable cavities located at the filling, suction, and dripping stations, heating and insulating the pen refill molds in these cavities. Low-temperature fluid flows sequentially forward from the turntable cavity located at the last cooling station, forming a tiered cooling system within the cooling station's cavity.

[0048] The above specific embodiments further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above are merely specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
