Description

Technical Field

[0001] This utility model belongs to the field of laundry detergent pod production technology, specifically relating to a laundry detergent pod filling mold and filling device. Background Technology

[0002] Laundry detergent pods are an innovative laundry product designed specifically for machine washing. They work on the same principle as liquid laundry detergent, primarily using nonionic surfactants. With a near-neutral pH, they are gentler on the skin and degrade quickly in the environment. Compared to traditional liquid laundry detergent, laundry detergent pods are convenient to use, leave hands clean, and one pod is enough to wash a load of clothes. They also feature a low-foaming, concentrated, and color-locking formula that makes rinsing easier.

[0003] Due to diversified market demand, the need for packaging laundry detergent pods representing the 26 letters of the alphabet is constantly emerging. However, currently, single-cavity laundry detergent pod products on the market are mainly filled automatically using roller-type laundry detergent pod packaging machines. Due to limitations in the filling channel and control system, a single main roller mold can often only fill one type of laundry detergent pod or those with only minor shape differences. According to the traditional main roller design, 26 sets of molds and filling systems are needed to accommodate the filling of 26 different shapes of laundry detergent pods. This results in a large number of molds, high manufacturing costs, and complex shape switching, making it difficult to meet actual production requirements. Using 26 sets of roller molds is also costly, involves complex shape switching, and requires 26 production cycles to collect all 26 letter-type laundry detergent pods, which is also insufficient for practical production needs. Utility Model Content

[0004] The purpose of this utility model is to overcome the existing technical defects and provide a laundry detergent pod filling mold. This mold can automatically fill all 26 letters on a single main roller or flatbed machine, saving mold manufacturing costs and switching costs during the production process, and realizing automated filling of all letters of laundry detergent pods.

[0005] In the first aspect, in order to solve the above-mentioned technical problems, this utility model provides a laundry detergent pod filling mold, including three first molds, second molds and third molds arranged in a row. Each mold has at least nine cavities recessed along its length, and all cavities include the shape of at least 26 letters. At least one vacuum hole is provided through the bottom of each cavity.

[0007] Furthermore, the nine cavities on one mold are shaped like the letters Z, H, B, G, O, E, J, X, and I; the nine cavities on another mold are shaped like the letters M, A, R, U, Q, F, L, Y, and S; and the nine cavities on the last mold are shaped like the letters W, V, K, C, N, D, P, T, and S. The cavities shaped like Z, M, and W in the three molds correspond sequentially; the cavities shaped like H, A, and V in the three molds correspond sequentially; the cavities shaped like B, K, and R in the three molds correspond sequentially; the cavities shaped like G, U, and C in the three molds correspond sequentially; the cavities shaped like O, Q, and N in the three molds correspond sequentially; the cavities shaped like E, F, and D in the three molds correspond sequentially; the cavities shaped like J, L, and P in the three molds correspond sequentially; the cavities shaped like X, Y, and T in the three molds correspond sequentially; and the cavities shaped like I and S in the three molds correspond sequentially.

[0008] Furthermore, one mold has nine cavities shaped like the letters Z, H, B, G, O, E, J, X, and I; another mold has nine cavities shaped like the letters M, A, R, U, Q, F, L, Y, and I; and the last mold has nine cavities shaped like the letters W, V, K, C, N, D, P, T, and S. The cavities shaped like Z, M, and W in the three molds correspond sequentially; the cavities shaped like H, A, and V in the three molds correspond sequentially; the cavities shaped like B, K, and R in the three molds correspond sequentially; the cavities shaped like G, U, and C in the three molds correspond sequentially; the cavities shaped like O, Q, and N in the three molds correspond sequentially; the cavities shaped like E, F, and D in the three molds correspond sequentially; the cavities shaped like J, L, and P in the three molds correspond sequentially; the cavities shaped like X, Y, and T in the three molds correspond sequentially; and the cavities shaped like I and S in the three molds correspond sequentially. Furthermore, the first cavities of the three molds are shaped like the letters Z, M, and W; the second cavities are shaped like the letters H, A, and V; the third cavities are shaped like the letters B, K, and R; the fourth cavities are shaped like the letters G, U, and C; the fifth cavities are shaped like the letters O, Q, and N; the sixth cavities are shaped like the letters E, F, and D; the seventh cavities are shaped like the letters J, L, and P; the eighth cavities are shaped like the letters X, Y, and T; and the ninth cavities of two molds are shaped like the letters I and S, while the ninth cavity of the other mold is shaped like either the letter I or S.

[0009] Secondly, this utility model also provides a laundry pod filling device, including a main roller shaft, wherein a plurality of sets of laundry pod filling molds as described in any one of the first aspects are arranged on the outer periphery of the main roller shaft.

[0010] Furthermore, the main roller shaft includes a main shaft and two circular support members, a first circular support member and a second circular support member, respectively fitted onto the front and rear ends of the main shaft. The two ends of the laundry pod filling mold are respectively located on the outer periphery of the first circular support member and the second circular support member.

[0011] Furthermore, the laundry pod filling device also includes a bracket disposed above the main roller shaft and extending along the length of the mold, wherein at least one filling head is provided on the bracket at the position corresponding to each cavity of the same mold.

[0012] Thirdly, this utility model also provides another laundry pod filling device, including a horizontal conveying mechanism, wherein the outer surface of the horizontal conveying mechanism is provided with a plurality of sets of laundry pod filling molds as described in any one of the first aspects.

[0013] Furthermore, the laundry pod filling device also includes a support frame disposed above the horizontal conveying mechanism and extending along the length of the mold.

The horizontal conveying mechanism includes two first chains and a second chain distributed at intervals, and a drive mechanism for driving the first chain and the second chain to run synchronously. The two ends of the laundry pod filling mold are respectively fixed to the outside of the first chain and the second chain.

[0014] This utility model has the following beneficial effects: In this invention, a laundry pod filling mold consisting of three arranged molds is used on a roller-type or flat-type automatic laundry pod packaging machine to replace the original single-shaped mold. This allows for the mixed filling of 26 English letter-shaped laundry pods during the rotation of the main roller or the conveying of the horizontal conveyor mechanism. This enables the existing automatic laundry pod packaging machine to produce 26 English letters at once on a single main roller or flat-plate machine, reducing the number of molds, reducing mold changeover time, saving mold manufacturing costs and changeover costs during production, and achieving fully automated filling of all-letter laundry pods.

[0015] Secondly, by placing letters with similar shapes, sizes, and widths on the same cavity in the three molds, the filling heads can be designed to accommodate different letter shapes and employ methods such as simultaneous filling from both sides, filling from the center, or filling from one side. For example, the letters Z, M, W, H, A, V, G, U, C, O, Q, and N corresponding to the first, second, fourth, and fifth cavities can be filled simultaneously from both sides using filling heads with double nozzles. The letters corresponding to the third, sixth, and seventh cavities can be filled from one side using filling heads with single nozzles, while the letters corresponding to the eighth and ninth cavities can be filled in the center using filling heads with single nozzles. By arranging the cavities in this way for the 26 letter shapes, the filling heads at different positions can accommodate the different letter flow paths, achieving uniform filling speed.

[0016] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and will become apparent from the description or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0018] To better understand the technical content of this utility model, the following will further introduce and explain this utility model in conjunction with the accompanying drawings and specific embodiments. It should be noted that if there are descriptions such as "first" and "second" in the text, they are used to distinguish different components, etc., and do not represent the order of priority, nor do they limit "first" and "second" to be different types.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1 like Figure 1 As shown in the figure, the laundry detergent pod filling mold of this embodiment includes three molds arranged in a row: a first mold 1, a second mold 2, and a third mold 3. Each mold has nine cavities recessed along its length, namely, the first cavity 11, the second cavity 12, the third cavity 13, the fourth cavity 14, the fifth cavity 15, the sixth cavity 16, the seventh cavity 17, the eighth cavity 18, and the ninth cavity 19. The nine cavities on the three molds correspond one-to-one. The three molds have a total of 27 cavities. All cavities include the shape of at least 26 letters, that is, there is one cavity with a repeating letter. At least one vacuum hole 10 is provided through the bottom of each cavity for connecting to an external vacuum pump. During the production of laundry detergent pods, the cavity is evacuated, so that the bottom film covering the surface of the mold can be quickly stretched and formed along the inner surface of the cavity.

[0021] In the above-mentioned case, when the laundry pod filling mold consisting of three arranged molds is used on a roller-type or flat-type laundry pod automatic packaging machine, it replaces the original single-shaped mold. This allows for the mixed filling of 26 English letter-shaped laundry pods during the rotation of the main roller or the conveying of the horizontal conveyor mechanism. In this way, the existing laundry pod automatic packaging machine can produce 26 English letters at once on a single main roller or flat-plate machine, reducing the number of molds, reducing mold changeover time, saving mold manufacturing costs and changeover costs during the production process, and realizing fully automated filling of all-letter pods.

[0022] In one embodiment, each mold has a vacuum groove 21 located outside the mold cavity at both ends for connecting to an external vacuum pump, which can be used to fix the edge of the bottom mold during the production of laundry pods.

[0023] In one embodiment, the nine cavities on one mold are shaped like the letters Z, H, B, G, O, E, J, X, and I; the nine cavities on another mold are shaped like the letters M, A, R, U, Q, F, L, Y, and S; and the nine cavities on the last mold are shaped like the letters W, V, K, C, N, D, P, T, and S. That is, there are two cavities shaped like the letter S among the 27 cavities. In this structure, firstly, the arrangement and position of the nine letters on a single mold can be arbitrarily changed; secondly, the arrangement of the letters on the three molds can also be interchanged. However, no matter how the order of the letters changes, the cavities shaped like the letters Z, M, and W in the three molds correspond sequentially, and the cavities shaped like the letters H, A, and V in the three molds... The mold cavities are arranged in a front-to-back correspondence. Specifically, the mold cavities in the shapes of letters B, K, and R in the three molds are arranged front-to-back; the mold cavities in the shapes of letters G, U, and C in the three molds are arranged front-to-back; the mold cavities in the shapes of letters O, Q, and N in the three molds are arranged front-to-back; the mold cavities in the shapes of letters E, F, and D in the three molds are arranged front-to-back; the mold cavities in the shapes of letters J, L, and P in the three molds are arranged front-to-back; the mold cavities in the shapes of letters X, Y, and T in the three molds are arranged front-to-back; and the mold cavities in the shapes of letters I and S in the three molds are arranged front-to-back. This letter distribution facilitates the design of the filling head on the laundry pod filling device, allowing different letter mold cavities in the same position within the three molds to be used simultaneously with the filling head in the same position.

[0024] In another embodiment, the nine cavities on one mold are shaped like the letters Z, H, B, G, O, E, J, X, and I; the nine cavities on another mold are shaped like the letters M, A, R, U, Q, F, L, Y, and I; and the nine cavities on the last mold are shaped like the letters W, V, K, C, N, D, P, T, and S. That is, there are two shapes for the letter I among the 27 cavities. Furthermore, the cavities for the letters Z, M, and W in the three molds correspond sequentially, and the cavities for the letters H, A, and V in the three molds... The shapes of the mold cavities correspond front to back in the three molds. Specifically, the shapes of the mold cavities for letters B, K, and R correspond front to back in the three molds; the shapes of the mold cavities for letters G, U, and C correspond front to back in the three molds; the shapes of the mold cavities for letters O, Q, and N correspond front to back in the three molds; the shapes of the mold cavities for letters E, F, and D correspond front to back in the three molds; the shapes of the mold cavities for letters J, L, and P correspond front to back in the three molds; the shapes of the mold cavities for letters X, Y, and T correspond front to back in the three molds; and the shapes of the mold cavities for letters I and S correspond front to back in the three molds. In this embodiment, the first mold cavity 11 of the three molds are shaped like the letters Z, M, and W, respectively; the second mold cavity 12 of the three molds are shaped like the letters H, A, and V, respectively; the third mold cavity 13 of the three molds are shaped like the letters B, K, and R, respectively; the fourth mold cavity 14 of the three molds are shaped like the letters G, U, and C, respectively; the fifth mold cavity 15 of the three molds are shaped like the letters O, Q, and N, respectively; the sixth mold cavity 16 of the three molds are shaped like the letters E, F, and D, respectively; the seventh mold cavity 17 of the three molds are shaped like the letters J, L, and P, respectively; the eighth mold cavity 18 of the three molds is shaped like the letters X, Y, and T, respectively; and the ninth mold cavity 19 of two molds are shaped like the letters I and S, respectively, while the ninth mold cavity of the other mold is shaped like either the letter I or S.

[0025] In other embodiments, depending on the roller-type or flat-type automatic laundry pod packaging machine used for the laundry pod filling mold, the first mold, the second mold, and the third mold can all be designed with a shape that is larger at the top and smaller at the bottom or with the same width at the top and bottom. The shape that is larger at the top and smaller at the bottom can better match the circular main roller in the roller-type automatic laundry pod packaging machine, and the shape with the same width at the top and bottom can better match the horizontal conveying mechanism in the flat-type automatic laundry pod packaging machine.

[0026] Example 2 like Figures 1 to 5 As shown, this embodiment provides a laundry pod filling device, including a main roller 4. The outer periphery of the main roller 4 is provided with a number of sets of laundry pod filling molds as described in Embodiment 1. That is, the three molds arranged in Embodiment 1, namely the first mold 1, the second mold 2 and the third mold 3, are combined into a set of laundry pod filling molds. Then, a number of sets of laundry pod filling molds are arranged circumferentially on the outer periphery of the main roller 4.

[0027] In one embodiment, such as Figures 2 to 5 As shown, the main roller shaft 4 includes a main shaft 41 and two first circular support members 42 and second circular support members 43 respectively fitted at the front and rear ends of the main shaft 41. The two ends of the laundry pod filling mold are respectively fixed on the outer periphery of the first circular support member 42 and the second circular support member 43. The main shaft 41, the first circular support member 42, the second circular support member 43 and the laundry pod filling mold form a circular main roller shaft, and a cavity is formed inside the main roller shaft.

[0028] In one embodiment, such as Figures 2 to 5 As shown, the laundry pod filling device also includes a support 5 located above the main roller 4 and extending along the length of the mold. The support 5 has a filling head 6 with at least one filling nozzle at each cavity of the same mold.

[0029] Specifically, the filling head 6 corresponding to the first, second, fourth, and fifth mold cavities has two filling nozzles arranged on the left and right sides, respectively corresponding to the two sides of the mold cavity, so that filling can be performed simultaneously on both sides of the first, second, fourth, and fifth mold cavities; the filling head 6 corresponding to the third, sixth, and seventh mold cavities has one filling nozzle, which is corresponding to one side of the mold cavity, forming a single-sided filling design; the filling head 6 corresponding to the eighth and ninth mold cavities also has one filling nozzle, which is corresponding to the middle of the mold cavity, forming a center filling design. Thus, by using different filling head designs, the filling channels of different letters on the three molds can be taken into account, and uniform filling can be achieved.

[0030] In one embodiment, due to the influence of the circumferential curved surface, only one support and a corresponding number of filling heads are provided above the main roller 4, so that the filling head 6 on the support can only fill the mold cavity on a single mold at the same time.

[0031] In one embodiment, the first mold, the second mold, and the third mold are all designed with a larger outer shape and a smaller inner shape, so as to facilitate cooperation with the first circular support and the second circular support to form a ring-shaped distribution of laundry pod filling molds.

[0032] In other embodiments, each filling head is connected to an external feeding mechanism (not shown in the figure) via a pipeline.

[0033] In other embodiments, the main shaft at the center of the main roller is connected to an external drive device (not shown) to perform a rotational action under the drive of the drive device.

[0034] In other embodiments, a vacuum pump (not shown in the figure) is provided inside the main roller. The vacuum pump is connected to the vacuum hole on each mold through a pipeline, and the pipeline on each mold is controlled to open and close by a separate solenoid valve, thus realizing individual control of vacuuming for each mold.

[0035] In other embodiments, a small vacuum pump can be provided on the inside of each mold and connected to the vacuum hole on the mold to achieve the purpose of vacuuming each mold individually.

[0036] Example 3 like Figure 1 as well as Figures 6 to 8 As shown, this utility model also provides another laundry pod filling device, including a horizontal conveying mechanism. The outer surface of the horizontal conveying mechanism is provided with several sets of laundry pod filling molds as described in Embodiment 1. That is, the three molds arranged in Embodiment 1, namely the first mold 1, the second mold 2 and the third mold 3, are combined into a set of laundry pod filling molds, and then several sets of laundry pod filling molds are arranged on the entire outer surface of the horizontal conveying mechanism.

[0037] In one embodiment, such as Figures 6 to 8 As shown, the horizontal conveying mechanism includes two first chains 71 and second chains 72 distributed at intervals, and a drive mechanism for driving the first chains 71 and second chains 72 to run synchronously. The two ends of the laundry pod filling mold are fixed to the outside of the first chains 71 and second chains 72 by fixing plates 73 respectively. The drive mechanism includes two sets of gears that mesh with the first chains 71 and second chains 72 respectively. Each gear set includes four gears 74 arranged in a four-corner distribution.

[0038] In one embodiment, such as Figures 6 to 8 As shown, the laundry pod filling device also includes a support 5 disposed above the horizontal conveying mechanism and extending along the length of the mold. The support 5 is provided with a filling head 6 having at least one filling nozzle 61 at each mold cavity corresponding to the same mold.

[0039] Specifically, such as Figures 6 to 8 As shown, the filling head 6 corresponding to the first, second, fourth, and fifth mold cavities has two filling nozzles arranged on the left and right sides, respectively corresponding to the two sides of the mold cavity, so that filling can be performed simultaneously on both sides of the first, second, fourth, and fifth mold cavities; the filling head 6 corresponding to the third, sixth, and seventh mold cavities has one filling nozzle, which is corresponding to one side of the mold cavity, forming a single-sided filling design; the filling head 6 corresponding to the eighth and ninth mold cavities also has one filling nozzle, which is corresponding to the middle of the mold cavity, forming a center filling design. Thus, by using different filling head designs, the filling channels of different letters on the three molds can be taken into account, and uniform filling can be achieved.

[0040] In one embodiment, the first mold, the second mold, and the third mold are all designed with the same width at the top and bottom to facilitate cooperation with the two horizontally conveying chains to form a flat laundry pod filling device.

[0041] In other embodiments, each filling head is connected to an external feeding mechanism (not shown in the figure) via a pipeline.

[0042] In other embodiments, gear 74 is connected to the rotating shaft of an external drive device (not shown) to drive the first chain and the second chain forward synchronously under the drive of the drive device.

[0043] In other embodiments, only the two corresponding gears can be connected to the rotating shaft of the external drive device (not shown in the figure), that is, the rotating shaft passes through the two corresponding gears, while the other gears are rotatably mounted on the external support (not shown in the figure).

[0044] In other embodiments, the vacuum hole on each mold is connected to an external vacuum pump (not shown in the figure) through a pipeline, and the pipeline on each mold is controlled to open and close by a separate solenoid valve, thus achieving individual control of the vacuuming of each mold.

[0045] In other embodiments, a small vacuum pump can be provided on the inside of each mold and connected to the vacuum hole on the mold to achieve the purpose of vacuuming each mold individually.

[0046] In other embodiments, a corresponding filling head may be provided above only one mold, so that only the same mold cavity can be filled at the same time; or multiple supports may be provided and a filling head may be provided on each support to achieve the purpose of filling multiple mold cavities at the same time.

[0047] The technical solutions provided by the embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the embodiments of this utility model. The description of the above embodiments is only for helping to understand the principles of the embodiments of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the embodiments of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
