[0052] Refer to Figure 1 and Figure 2, the present utility model provides a filling device for cosmetic packaging bags, which is used for filling cosmetic packaging bags. The cosmetic packaging bag has a first cosmetic packaging bag, a second cosmetic packaging bag, and a connecting bag body connected between the first cosmetic packaging bag and the second cosmetic packaging bag; the filling device for the cosmetic packaging bag includes:

[0053] Base 1:

[0054] A conveying mechanism 2, arranged on the base 1, for conveying the aforementioned cosmetic packaging bags;

[0055] A first bag-opening mechanism 3, arranged on the base 1, for opening the bag mouth of the first cosmetic packaging bag and the bag mouth of the second cosmetic packaging bag;

[0056] A filling mechanism 4, including a bag-entering driving part 41, a first filling head 42, and a second filling head 43. The bag-entering driving part 41 is arranged on the base 1, and the first filling head 42 and the second filling head 43 are arranged at intervals at the output end of the bag-entering driving part 41;

[0057] Among them, the bag-entering driving part 41 is used to drive the first filling head 42 to move into the first cosmetic packaging bag with the bag mouth opened and drive the second filling head 43 to move into the second cosmetic packaging bag with the bag mouth opened;

[0058] The first filling head 42 is used to fill the first cosmetic liquid into the first cosmetic packaging bag;

[0059] The second filling head 43 is used to fill the second cosmetic liquid into the second cosmetic packaging bag.

[0060] In this embodiment, the filling device for the cosmetic packaging bag proposed by the solution of the present application is mainly applied to a cosmetic packaging bag having a first cosmetic packaging bag, a second cosmetic packaging bag, and a connecting bag body connecting the two, and fills the cosmetic liquids into the respective cosmetic packaging bags of the cosmetic packaging bag with this design.

[0061] The main components of the cosmetic packaging bag filling equipment proposed in this application include a conveying mechanism 2, a first bag-opening mechanism 3, and a filling mechanism 4. The conveying mechanism 2 is responsible for transporting the packaging bags with the first cosmetic packaging bag, the second cosmetic packaging bag, and the connecting bag body to a designated position. The first bag-opening mechanism 3 is used to open the bag mouths of the first cosmetic packaging bag and the second cosmetic packaging bag, so that each sealed cosmetic packaging bag is ready to receive filling. The filling mechanism 4 includes a bag-in driving member 41, a first filling head 42, and a second filling head 43. The bag-in driving member 41 is used to drive the first filling head 42 to move and extend into the first cosmetic packaging bag with an opened bag mouth, and the bag-in driving member 41 is also used to drive the second filling head 43 to move and extend into the second cosmetic packaging bag with an opened bag mouth; the first filling head 42 is used to fill the first cosmetic liquid into the first cosmetic packaging bag, and the second filling head 43 is used to fill the second cosmetic liquid into the second cosmetic packaging bag.

[0062] The working process of the cosmetic packaging bag filling equipment proposed in the solution of this application is as follows:

[0063] Conveying: The conveying mechanism 2 moves the cosmetic packaging bag from the starting position to the working area where the first bag-opening mechanism 3 and the filling mechanism 4 are located. This working area can be called the filling station.

[0064] Bag opening: After the cosmetic packaging bag is conveyed to the position of the first bag-opening mechanism 3, the first bag-opening mechanism 3 opens the bag mouths of the first cosmetic packaging bag and the second cosmetic packaging bag of the cosmetic packaging bag.

[0065] Filling: The bag-in driving member 41 in the filling mechanism 4 drives the first filling head 42 to extend into the first cosmetic packaging bag with an opened bag mouth, and drives the second filling head 43 to extend into the second cosmetic packaging bag with an opened bag mouth.

[0066] The first filling head is used to fill cosmetics into the first cosmetic packaging bag, while the second filling head is used to fill cosmetics into the second cosmetic packaging bag. After each filling head completes filling, it is driven by the bag-in driving member 41 to withdraw from each packaging bag and return to its original position away from the bag mouth of each packaging bag.

[0067] After filling is completed, the cosmetic packaging bag is continuously conveyed to the next processing step, which may be sealing, packaging, etc.

[0068] The solution of this application realizes the following effects by setting the cosmetic packaging bag filling equipment with the above structure:

[0069] First, improve efficiency: Through the automated processes of conveying, bag opening, and filling, the efficiency of cosmetic filling is greatly improved, reducing the time and cost of manual operation.

[0070] Second, ensure accuracy: The present application can precisely control the filling head through the controller to ensure that the filling volume of each packaging bag is consistent, avoiding human errors and improving the consistency of product quality.

[0071] Third, adapt to diverse needs: The equipment of the present application can handle composite cosmetic packaging bags with a first cosmetic packaging bag, a second cosmetic packaging bag, and a connecting bag body connected between the first cosmetic packaging bag and the second cosmetic packaging bag, and is applicable to the filling requirements of two-in-one cosmetics or even cosmetic packaging bags with multiple independently packaged bags connected. This enhances the applicability and flexibility of the equipment. When applying to cosmetic packaging bags with more than two independently packaged bags, the number of filling heads needs to be correspondingly increased.

[0072] In the solution of the present application, a conveying mechanism is provided to convey a cosmetic packaging bag with a first cosmetic packaging bag, a second cosmetic packaging bag, and a connecting bag body to a first bag-opening mechanism 3. The first bag-opening mechanism 3 opens the bag mouth of the first cosmetic packaging bag and the bag mouth of the second cosmetic packaging bag to facilitate subsequent filling operations. Then, the conveying mechanism 4 conveys the first cosmetic packaging bag and the second cosmetic packaging bag with the bag mouths opened to positions corresponding to a first filling head 42 and a second filling head 43. The bag-in driving member 41 drives the first filling head 42 to extend into the first cosmetic packaging bag for filling the first cosmetic liquid and drives the second filling head 43 to extend into the second cosmetic packaging bag for filling the second cosmetic liquid, thereby realizing the simultaneous filling of the cosmetic packaging bag with the first cosmetic packaging bag and the second cosmetic packaging bag, and solving the problems of the relatively cumbersome sequential filling steps and low filling efficiency existing in the filling equipment provided by the related technology.

[0073] Refer to Figure 1 and Figure 3 In some embodiments, the cosmetic packaging bag filling equipment proposed in the embodiment of the present utility model further includes a bearing plate 8. The machine base includes a first mounting surface 11 and a second mounting surface 12. The first mounting surface 11 is horizontally arranged, and the second mounting surface 12 is connected to the first mounting surface and is obliquely upwardly arranged at an inclination angle of 45° ± 10° relative to the first mounting surface 11;

[0074] The conveying mechanism 2 is arranged on the second mounting surface 12, and the bearing plate 8 is arranged on the side of the conveying mechanism adjacent to the first mounting surface 11 in the vertical direction. The bearing plate 8 is used to support the side of the cosmetic packaging bag on the conveying mechanism 2 that is opposite to the bag mouths of the first cosmetic packaging bag and the second cosmetic packaging bag, so that the cosmetic packaging bag is supported on the conveying mechanism 2 and the bearing plate 8 in a posture where the bag mouths of the first cosmetic packaging bag and the second cosmetic packaging bag are both obliquely upward at an inclination angle of 45° ± 10°.

[0075] In this embodiment, the machine base 1 includes two mounting surfaces: the first mounting surface 11 and the second mounting surface 12. The first mounting surface 11 is horizontally arranged, and the second mounting surface 12 is obliquely upward arranged relative to the first mounting surface 11 at an inclination angle of 45° ± 10°. The conveying mechanism 2 is arranged on the inclined second mounting surface 12. Since the bag mouth of the cosmetic packaging bag needs to be set upward so that the cosmetic liquid filled in the cosmetic packaging bag will not pour out, and in the solution of this application, by placing the cosmetic packaging bag on the inclined conveying mechanism 2, the bearing plate 8 is arranged on the side of the conveying mechanism adjacent to the first mounting surface 11 in the vertical direction, and the bearing plate 8 supports the side of the cosmetic packaging bag on the conveying mechanism 2 facing away from the bag mouth, so that the bag mouth of the cosmetic packaging bag always maintains an inclined state at an inclination angle of 45° ± 10° during transportation.

[0076] First, the conveying mechanism 2 moves the cosmetic packaging bag from the initial position to the position of the first bag opening mechanism 3. Since the second mounting surface 12 is inclined, the bag mouth of the cosmetic packaging bag is inclined upward.

[0077] Then, the first bag opening mechanism 3 performs a bag opening operation on the first cosmetic packaging bag and the second cosmetic packaging bag with the bag mouth upward to ensure that the bag mouth is completely opened and ready to receive filling.

[0078] Next, the conveying mechanism 2 continues to move the packaging bag with the bag mouth opened to the filling position. At this time, the bag-in driving member 41 drives the first filling head 42 to extend into the first cosmetic packaging bag with the bag mouth opened to fill the first cosmetic liquid, and drives the second filling head 43 to extend into the second inner bag of the cosmetic packaging bag with the bag mouth opened to fill the second cosmetic liquid.

[0079] The following effects are achieved through the above settings in this application:

[0080] Using the conveying system composed of the inclined conveying mechanism 2 and the bearing plate 8, when the cosmetic packaging bag is placed on the conveying mechanism 2, the bag mouth of the cosmetic packaging bag is inclined upward, and the side of the cosmetic packaging bag facing away from the bag mouth is supported by the bearing plate 8, so that the cosmetic packaging bag can be naturally inclined upward without manual or mechanical clamping to fix the cosmetic packaging bag.

[0081] Second, the stability of the whole operation process is improved, and the risk of the packaging bag moving or tipping over during transportation and filling is reduced.

[0082] In some embodiments, the inclination angle of 45° ± 10° is a relatively preferred setting. According to the actual needs of those skilled in the art, inclination angles such as 30° and 60° can be selected, but it is necessary to ensure that the filled cosmetic liquid will not pour out due to the inclination angle after the cosmetic packaging bag is filled.

[0083] Refer to Figures 1 to 5, in some embodiments, the conveying mechanism 2 proposed in the embodiments of the present utility model includes:

[0084] A support assembly 21, including two supports 211 spaced apart on the second mounting surface 12;

[0085] A first driving member 22, disposed on one support 211, and its output end extends between the two supports 211;

[0086] A conveyor belt assembly 23, located between the two supports 211, includes a driving pulley 231, a driven pulley 232 and a belt body 233. The driving pulley 231 is rotatably connected to the two supports and is drivingly connected to the output end of the first driving member 22. The driven pulley 232 is spaced apart from the driving pulley 231 and is rotatably connected to the two supports 211. The belt body 233 is parallel to the second mounting surface, and the belt body 233 is annularly sleeved on the driving pulley 231 and the driven pulley 232. The belt body 233 is used to carry the cosmetic packaging bags and convey the cosmetic packaging bags under the drive of the first driving member 22.

[0087] In this embodiment, the belt body 233 is parallel to the second mounting surface 12, and the lower surface of the cosmetic packaging bag contacts the belt body 233. When the output end of the first driving member 22 starts to output driving force, it drives the driving pulley 231 connected thereto to rotate. The rotation of the driving pulley 231 drives the annular belt body 233 to move, thereby driving the driven pulley 232 connected to the belt body 233 to move. In this process, the belt body 233 carries the cosmetic packaging bags and conveys them along a set path. When the belt body 233 rotates around the driving pulley 231 and the driven pulley 232, the cosmetic packaging bags move on the belt body 233. The circular motion enables multiple bags to be continuously conveyed.

[0088] In some embodiments, the first driving member 22 can be a stepper motor or a servo motor.

[0089] Refer to Figure 5 , in some embodiments, the conveyor belt assembly 23 proposed in the embodiments of the present utility model further includes a plurality of partitions 234. The plurality of partitions 234 are spaced apart along the entire outer peripheral wall of the belt body 233, and the belt body 233 between any two adjacent partitions 234 is used to carry a cosmetic packaging bag.

[0090] In this embodiment, the conveyor belt assembly 23 is provided with a plurality of spaced partitions 234 on the belt body 233. The belt body 233 between any two adjacent partitions 234 can accommodate a cosmetic packaging bag. It can be used to carry multiple cosmetic packaging bags at the same time, and the presence of the partitions 234 effectively separates each cosmetic packaging bag, preventing them from interfering with or colliding with each other during the conveying process, so as to ensure stability and non-interference during the conveying of multiple cosmetic packaging bags.

[0091] During the assembly of the conveyor belt assembly 23, the partition plates 234 are evenly spaced along the entire outer peripheral wall of the belt body 233, ensuring that there is sufficient space between every two adjacent partition plates to accommodate cosmetic packaging bags. When it is necessary to replace the cosmetic packaging bags of different sizes for production, the belt body 233 with a larger spacing of the partition plates 234 can be replaced.

[0092] When the first driving member 22 is started, it drives the driving pulley 231 to drive the belt body 233 to move. As the belt body 233 moves, each partition plate 234 also moves along the conveying path of the belt body 233.

[0093] A cosmetic packaging bag can be placed on the belt body 233 between any two adjacent partition plates 234. When the belt body 233 rotates, the two partition plates 234 limit the cosmetic packaging bag therebetween, making it not easy to move or slip during transportation and not interfering with adjacent cosmetic packaging bags.

[0094] The design of multiple spaced partition plates 234 ensures that even under high-speed transportation, collisions or mutual interference do not occur between multiple cosmetic packaging bags, avoiding damage to the cosmetic packaging bags caused by interference.

[0095] The solution of this application realizes the following effects by setting the conveyor belt assembly 23 with the above structure:

[0096] Improve the load-bearing capacity: The structure of multiple spaced partition plates 234 enables the conveyor belt assembly 23 to carry multiple packaging bags simultaneously, significantly improving production efficiency and resource utilization rate.

[0097] Enhance stability: Due to the effective restraint of the partition plates 234 on the packaging bags, the risk of the cosmetic packaging bags tipping or slipping during transportation is reduced, improving the overall transportation safety.

[0098] Reduce losses: Multiple spaced partition plates 234 reasonably isolate each cosmetic packaging bag during transportation, avoiding losses caused by collisions, thereby reducing production costs.

[0099] Facilitate management and adjustment: The flexibility of the partition layout enables operators to adjust the spacing size according to actual needs to adapt to different types or sizes of packaging bags, providing better flexibility in use.

[0100] Refer to Figure 1 and Figure 6 In some embodiments, the first bag-opening mechanism 3 proposed by the embodiment of the present utility model includes:

[0101] The first adsorption assembly 31 is arranged on the first mounting surface 11 and includes a first suction cup 311 and a second suction cup 312. The first suction cup 311 and the second suction cup 312 are located above the belt body 233, and the first suction cup 311 and the second suction cup 312 are respectively arranged corresponding to the upper surface of the first cosmetic packaging bag and the upper surface of the second cosmetic packaging bag.

[0102] The second adsorption assembly 32 is arranged on the second mounting surface 12 and includes a third suction cup 321 and a fourth suction cup 322. The third suction cup 321 and the fourth suction cup 322 are located below the belt body 233, and the third suction cup 321 and the fourth suction cup 322 are respectively arranged corresponding to the upper surface of the second cosmetic packaging bag and the lower surface of the second cosmetic packaging bag.

[0103] The bag-opening driving member 33 is arranged on the machine base 1. The output end of the bag-opening driving member 33 is connected to the first adsorption assembly 31 and the second adsorption assembly 32. The bag-opening driving member 33 is used to drive the first adsorption assembly 31 and the second adsorption assembly 32 to move towards or away from each other, so as to perform bag-opening treatment on the cosmetic packaging bags on the conveying mechanism 2.

[0104] In this embodiment, the first bag-opening mechanism 3 opens the cosmetic packaging bag through adsorption and moving operations for subsequent filling or treatment. The first adsorption assembly 31 and the second adsorption assembly 32 respectively form suction forces on the upper and lower surfaces of the packaging bag. Driven by the bag-opening driving member 33, the back-and-forth movement of the upper and lower suction cups is promoted to open the packaging bag. The use of the suction cups makes the bag-opening process physically safer and more efficient, avoiding damage or unevenness that may be caused by manual bag-opening.

[0105] In the solution of this application, the bag mouth part of the cosmetic packaging bag extends out of the belt body 233, and the rest is carried on the belt body 233. The suspended setting of the bag mouth part facilitates the first bag-opening mechanism 3 to adsorb the bag mouth part.

[0106] The working process of the first bag-opening mechanism 3 proposed in the solution of this application is as follows:

[0107] Packaging bag positioning: Before the bag-opening process, the cosmetic packaging bag is first conveyed to the conveying mechanism 2 and positioned within the action range of the first adsorption assembly 31 and the second adsorption assembly 32.

At the same time, it also drives the third suction cup 321 of the second adsorption assembly 32 to contact the upper surface of the second cosmetic packaging bag, and drive the fourth suction cup 322 to contact the lower surface of the second cosmetic packaging bag. Each suction cup contacts the bag mouth of the cosmetic packaging bag, and then respectively adsorbs the upper surface and the lower surface of each packaging bag through the vacuum pumping effect.

[0109] Bag opening drive starts: The bag opening drive member 33 starts to drive the first adsorption assembly 31 and the second adsorption assembly 32 to move away from each other to open the bag mouth.

[0110] Bag opening completed: Under the operation of the first adsorption assembly 31 and the second adsorption assembly 32, the packaging bag for cosmetics is opened to form an opening, enabling it to receive subsequent filling.

[0111] Suction cup release: Once the bag opening is completed, the suction cups of the first adsorption assembly 31 and the second adsorption assembly 32 stop sucking vacuum, and the packaging bag for cosmetics remains in the open state, ready for the next operation.

[0112] The solution of this application realizes the following effects by setting the first bag opening mechanism 3 with the above structure:

[0113] Efficient bag opening: The design of the first bag opening mechanism 3 enables the packaging bag for cosmetics to complete the bag opening process quickly and effectively, reducing the complexity of manual operations and improving production efficiency.

[0114] Reduced breakage: By using adsorption technology, the packaging bag will not be subjected to excessive tension or compression during the bag opening process, reducing the risk of damage to the packaging bag and maintaining the integrity of the product inside the package.

[0115] Flexible adaptability: Due to the design of the adsorption assembly, the first bag opening mechanism 3 can adapt to packaging bags for cosmetics of different sizes and shapes, showing strong flexibility.

[0116] In summary, through the coordinated action of the first adsorption assembly 31, the second adsorption assembly 32 and the bag opening drive member 33, the first bag opening mechanism 3 realizes efficient bag opening processing of the packaging bag for cosmetics, optimizes the production process, improves product quality, reduces manual intervention, and improves production efficiency.

[0117] Refer to Figure 1 、 Figure 7 and Figure 8 In some embodiments, the filling equipment for the packaging bag for cosmetics proposed in the embodiment of the present utility model further includes a stop mechanism 5 and a blanking buffer mechanism 6. The blanking buffer mechanism 6 is located below the conveying mechanism 2, and the stop mechanism 5 is arranged on the machine base and is located between the blanking buffer mechanism 6 and the conveying mechanism 2;

[0118] Among them, the stop mechanism 5 is used to block or release the packaging bag for cosmetics after filling, so that the packaging bag for cosmetics after filling is cached on the conveying mechanism 2 or conveyed to the blanking buffer mechanism 6, and the blanking buffer mechanism 6 is used to receive the packaging bag for cosmetics after filling.

[0119] In this embodiment, the main function of the stop mechanism 5 is to control the destination of the cosmetic packaging bags after filling. The stop mechanism 5 is located between the blanking buffer mechanism 6 and the conveying mechanism 2, and implements whether to block or release the filled cosmetic packaging bags through an adjustable mechanism (such as moving, lifting, etc.). The stop mechanism 5 ensures that the cosmetic packaging bags can be temporarily retained at the required position after filling, or flow to the blanking buffer mechanism 6 at an appropriate time. The main function of the blanking buffer mechanism 6 is to receive the cosmetic packaging bags released from the conveying mechanism 2 and perform temporary storage, providing space for subsequent processing steps (such as subsequent bag taking, boxing, etc.).

[0120] The working process of the stop mechanism 5 is as follows:

[0121] Initial state: When the cosmetic packaging bag is conveyed to the filling completion position through the conveyor belt assembly 23, the stop mechanism 5 is in the initial state, ready to receive the upcoming cosmetic packaging bag.

[0122] Filling completion detection: When the upstream filling mechanism completes the filling of the cosmetic packaging bag, the stop mechanism 5 reacts according to the instructions of the automation system, and may be monitored through sensors or control systems.

[0123] Release or block: According to the set working mode, the stop mechanism 5 can choose to release or block:

[0124] Release state: If a release instruction is received, the stop mechanism 5 retracts or opens, enabling the filled cosmetic packaging bag to flow smoothly to the blanking buffer mechanism 6.

[0125] Blocking state: If it is necessary to keep the cosmetic packaging bag in the current position (for example, waiting for the next processing step), the stop mechanism 5 blocks the cosmetic packaging bag to keep it on the conveying mechanism 2.

[0126] The working process of the blanking buffer mechanism 6 is as follows:

[0127] Receiving function: After the stop mechanism 5 releases, the filled cosmetic packaging bag flows to the blanking buffer mechanism 6 under the action of gravity.

[0128] Storage and preparation: The blanking buffer mechanism 6 stores the received cosmetic packaging bags, keeps them neatly stacked, avoids the bags from toppling or getting disordered, and prepares for subsequent automated processing steps.

[0129] This application realizes the following effects by setting the stop mechanism 5 and the blanking buffer mechanism 6 with the above structures: The combined design of the stop mechanism 5 and the blanking buffer mechanism 6 ensures the high-efficiency, safety and controllability of the filling and transfer process of the cosmetic packaging bags.

[0130] Refer to Figure 1 、 Figure 7 andFigure 8 , in some embodiments, the stopper mechanism 5 proposed in the embodiments of the present utility model includes a lifting drive member 51 and a baffle 52. The lifting drive member 51 is arranged on the conveying mechanism 2, and the baffle 52 is arranged at the output end of the lifting drive member 51;

[0131] The lifting drive member 51 is used to drive the baffle 52 to move to block the filled cosmetic packaging bag so that it remains on the conveying mechanism 2, and is also used to drive the baffle 52 to move to release the filled cosmetic packaging bag on the conveying mechanism 2 into the blanking buffer mechanism 6.

[0132] In this embodiment, the main function of the stopper mechanism 5 is to control the position of the baffle 52 through the lifting drive member 51, so as to realize the blocking or release of the cosmetic packaging bag. By changing the state of the baffle 52, it can effectively determine whether the packaging bag remains on the conveyor belt body 233 or flows into the blanking buffer mechanism 6. This design can achieve automatic control and improve the flexibility and accuracy of operation.

[0133] The working process of the stopper mechanism 5 proposed in the solution of this application is as follows:

[0134] State initialization: Before the work starts, the lifting drive member 51 and the baffle 52 are in a ready state. The initial position of the baffle 52 may be in a closed state to block the packaging bag.

[0135] Filling completion instruction: When the cosmetic packaging bag is filled on the belt body 233, the control system sends a signal to the lifting drive member 51 to instruct it to perform corresponding actions.

[0136] Baffle movement: The lifting drive member 51 starts according to the control instruction and pushes the baffle 52 to move:

[0137] Blocking state: If it is necessary to keep the filled packaging bag on the belt body 233 at this time, the baffle 52 rises to block the packaging bag from moving downward.

[0138] Release state: If it is necessary to release the packaging bag to the blanking buffer mechanism 6, the baffle 52 descends to allow the packaging bag to smoothly flow into the blanking buffer mechanism under the action of gravity.

[0139] Feedback and adjustment: During the whole process, sensors may monitor the position of the packaging bag and feedback to the control system, so as to realize dynamic adjustment to ensure high efficiency and accuracy and ensure the correct flow direction of the cosmetic packaging bag.

[0140] The solution of this application realizes the following effects by setting the stopper mechanism 5 with the above structure:

[0141] The stopper mechanism 5 realizes the efficient management of the filled packaging bags through the lifting mechanism, can quickly respond to the needs of the production line, and ensure the uninterrupted operation. And according to different production requirements, the lifting of the baffle 52 makes the whole process highly flexible and can adapt to different types of packaging bags and production rhythms.

[0142] Referring Figure 5 and Figure 7 , in some embodiments, the blanking buffer mechanism 6 proposed in the embodiment of the present invention includes a second base 61, at least one buffer spring 62 and a second driving member 63. The second driving member 63 is disposed on the second base 61. The second base 61 is recessed with a groove. The buffer spring 62 is disposed in the groove. One end of the buffer spring is rotatably connected to the side wall of the groove, and the other end of the buffer spring is connected to the output end of the second driving member 63. There are a plurality of coils arranged at intervals between the two ends of the buffer spring, and any two adjacent coils are used to accommodate a filled cosmetic packaging bag;

[0143] Wherein, the second driving member 63 is used to drive the buffer spring to rotate, so that the buffer spring drives the filled cosmetic packaging bag thereon to move in the horizontal direction.

[0144] In this embodiment, the second driving member 63 is installed on the second base 61 and is responsible for driving the buffer spring 62 to rotate. The second driving member 63 can be a motor, a cylinder or other types of driving devices. The buffer spring 62 is installed in the groove of the second base 61, one end is rotatably connected to the side wall of the groove, and the other end is connected to the output end of the second driving member 63. The buffer spring 62 can rotate in the groove.

[0145] The buffer spring 62 has a plurality of continuous coils, and there is an end pitch between the coils. The pitch interval between each coil accommodates a filled cosmetic packaging bag. When the spring rotates, each packaging bag is independently accommodated between two coils and remains stable. In some embodiments, two identical buffer springs 62 can be provided to adapt to larger cosmetic packaging bags.

[0146] The filled cosmetic packaging bag enters the blanking buffer mechanism 6 from the filling mechanism 4 and is placed between the first coil and the second coil of the buffer spring 62.

[0147] The second driving member 63 is started to drive the buffer spring 62 to rotate. The buffer spring 62 drives the filled cosmetic packaging bag thereon to move in the horizontal direction, conveys the packaging bag forward from the filling position, and moves it between the second coil and the third coil. The subsequent cosmetic packaging bags fall between the first coil and the second coil through the conveying mechanism 2, and the second driving member 63 continuously drives to horizontally move the cosmetic packaging bag to the next process position.

[0148] The solution of this application realizes the following effects by setting up the blanking buffer mechanism 6 with the above structure:

[0149] The cosmetic packaging bags can be cached on the buffer spring 62, and by rotating the buffer spring 62 through the second driving member 63, the cosmetic packaging bags can move quickly and continuously, improving the overall production efficiency.

[0150] At the same time, the design of the blanking buffer mechanism 6 takes into account space utilization. The structure combining the vertical and horizontal directions enables it to work efficiently in a smaller area, avoiding occupying too much production space.

[0151] Furthermore, the design of the buffer spring 62 ensures that the packaging bags are well supported during the movement, reducing possible tipping or damage phenomena, and enhancing the stability of the packaging bags during the conveying process.

[0152] In some embodiments, the second driving member 63 can be connected to a controller, and the controller can precisely control the conveying speed and interval of the packaging bags to adapt to different production requirements and rhythms.

[0153] Refer to Figure 1 , in some embodiments, the cosmetic packaging bag filling equipment proposed in the embodiment of the present utility model further includes a second bag opening mechanism 9 and a bag expanding mechanism 7 provided on the machine base 1. The bag expanding mechanism 7 and the filling mechanism 44 are arranged in sequence along the conveying direction of the conveying mechanism 22, wherein:

[0154] The conveying mechanism 2 is used to sequentially convey the cosmetic packaging bags to the pre-bag opening station and the filling station;

[0155] The second bag opening mechanism 9 is used to open the bag mouths of the first cosmetic packaging bag and the second cosmetic packaging bag located at the pre-bag opening station;

[0156] The bag expanding mechanism 7 is used to expand the inner cavity of the first cosmetic packaging bag located at the pre-bag opening station and with the bag mouth opened by the second bag opening mechanism 9, and is used to expand the inner cavity of the second cosmetic packaging bag located at the pre-bag opening station and with the bag mouth opened by the second bag opening mechanism 9;

[0157] The first bag opening mechanism 3 is used to open the bag mouths of the first cosmetic packaging bag and the second cosmetic packaging bag located at the filling station;

[0158] The filling mechanism 4 is used to fill cosmetics into the first cosmetic packaging bag located at the filling station and with the bag mouth opened by the first bag opening mechanism 3, and is used to fill cosmetics into the second cosmetic packaging bag located at the filling station and with the bag mouth opened by the first bag opening mechanism 3.

[0159] In this embodiment, the second bag opening mechanism 3 may adopt the same structure and setting position as the first bag opening mechanism 3 described in the above embodiment.

[0160] Reference Figure 1 and Figure 9 In some embodiments, the bag expanding mechanism 7 proposed in the embodiment of the utility model includes a bag expanding driving component 71, a first bag expanding component 72 and a second bag expanding component 73. The bag expanding driving component 71 is arranged on the machine base, and the first bag expanding component 72 and the second bag expanding component 73 are arranged at the output end of the bag expanding driving component 71. The bag expanding driving component 71 is used to drive the first bag expanding component 72 to extend into the first cosmetic packaging bag after the bag mouth is opened by the second bag opening mechanism 9 to expand the inner cavity of the first cosmetic packaging bag and to drive the second bag expanding component 73 to extend into the second cosmetic packaging bag after the bag mouth is opened by the second bag opening mechanism 9 to expand the inner cavity of the second cosmetic packaging bag.

[0161] In this embodiment, the bag expansion mechanism 7 drives the first bag expansion member 72 to enter the first cosmetic packaging bag after the bag opening is opened and drives the second bag expansion member 73 to enter the second cosmetic packaging bag after the bag opening is opened, thereby expanding the inner cavity of the cosmetic packaging bag.

[0162] The working process of the bag expansion mechanism 7 proposed in this application is as follows:

[0163] Driving of the bag expansion drive 71: The bag expansion drive 71 is installed on the machine base and is responsible for providing power to drive the first bag expansion member 72 and the second bag expansion member 73 to enter the corresponding cosmetic packaging bag. The bag expansion drive can be a motor, a cylinder or other devices.

[0164] The action of the first bag expanding component 72 and the second bag expanding component 73: after the second bag opening mechanism 9 opens the bag openings of the first cosmetic packaging bag and the second cosmetic packaging bag, the bag expanding driving component 71 is started to push the first bag expanding component 72 into the first cosmetic packaging bag and drive the second bag expanding component 73 into the second cosmetic packaging bag.

[0165] The first bag expansion member 72 and the second bag expansion member 73 can keep the packaging bag in an expanded state by expanding the inner cavity. In some embodiments, after the first bag expansion member 72 and the second bag expansion member 73 enter the bag, the inner cavity of the bag can be expanded by a mechanical structure (such as a support rod, an air bag, etc.) provided on the bag expansion member.

[0166] After the bag expansion is completed, the bag expansion member is driven away from the packaging bag by the bag expansion driving member 71, and the bag opening naturally maintains a certain expansion state. The conveying mechanism 2 conveys the cosmetic packaging bag with the bag opening in the expanded state to the filling station for filling.

[0167] The present application achieves the following effects by providing the bag expansion mechanism of the above structure:

[0168] The bag - expanding mechanism expands the inner cavity of the packaging bag by its own structure or by setting mechanical structures (such as airbags, struts) when it extends into the packaging bag, ensuring that the filling head can smoothly enter the bag, thereby improving the filling accuracy and efficiency.

[0169] Improving filling accuracy and efficiency: Through the bag - expanding operation, the inner cavity of the bag remains in an expanded state, enabling the filling head to accurately enter the bag, ensuring the inflow of the cosmetic liquid to be filled, and avoiding filling failures caused by liquid overflow or the closing of the bag mouth.

[0170] Stability and consistency: The automated bag - expanding operation ensures that the degree of expansion of each packaging bag is consistent, improving the stability of the entire production line and the consistency of the products.

[0171] Refer to Figure 1 In some embodiments, the filling equipment for cosmetic packaging bags proposed by the present utility model further includes a sealing device 10. The sealing device 10 is used to seal the bag mouths of the first cosmetic packaging bag and the second cosmetic packaging bag. After the cosmetic packaging bag goes through the filling process, the conveying mechanism sends the filled product packaging bag to the position of the sealing device 10. At this time, the bag mouth of the packaging bag is in an open state and waiting to be sealed. The sealing device 10 is usually equipped with sensors to automatically detect the arrival of the packaging bag and the accuracy of the bag mouth. If the sensor detects that the bag mouth position is correct, the sealing operation is triggered.

[0172] According to the type of packaging material, the sealing device 10 initiates the corresponding sealing method:

[0173] Heat - sealing: For heat - sealable materials, the equipment pre - heats the bag - mouth area to the melting point of the material through a heating device, causing the materials on both sides of the bag mouth to fuse together to form a tight seal.

[0174] Cold - sealing: For some high - quality packaging materials, the equipment can use cold - sealing technology to form a seal in the bag - mouth area through a pressing method.

[0175] During heat - sealing or cold - sealing, the sealing device 10 applies a certain pressure (such as using a pressure wheel, clamp, etc.) and maintains a certain time to ensure that the sealing materials are in full contact and complete bonding. This step is crucial for the sealing effect.

[0176] During heat - sealing, the melted material solidifies as it cools after the sealing is completed, forming a stable sealing effect. At this stage, some equipment may be equipped with a cooling system to help accelerate the solidification of the seal.

[0177] After the sealing is completed, the sealing device 10 can automatically detect the quality of the seal to ensure that there is no unsealed or incomplete situation. Some equipment may be equipped with a visual inspection system for real - time monitoring.

[0178] After ensuring that the sealing quality is qualified, the finished product packaging bags will be conveyed to the next process, which may be distribution, storage, or further packaging operations.

[0179] After the sealing device 10 completes the sealing, it is ready to enter the next working cycle. Usually, the device has an automatic cleaning function to ensure that the sealing of the next packaging bag is not contaminated.

[0180] In some embodiments, the sealing device 10 can be arranged between the feeding buffer mechanism 6 and the filling mechanism 4, and the sealing is carried out immediately after filling to ensure good protection of the filled cosmetics.

[0181] The above are only partial or preferred embodiments of the present utility model. Neither the text nor the drawings can limit the protection scope of the present utility model. Any equivalent structural transformation made by using the content of the specification and drawings of the present utility model under the overall concept of the present utility model, or any direct / indirect application in other related technical fields is included in the protection scope of the present utility model.
