Description

Technical Field

[0001] The utility model relates to the technical field of filling equipment, and particularly relates to a filling valve control mechanism for a laundry bead packaging machine. Background Art

[0002] A laundry bead is a bagged laundry detergent product in the shape of a bead formed by wrapping laundry detergent with a film. Its production process is to cover the bottom film on the surface of a drum mold, and then the drum mold sucks vacuum and plastically forms a cavity for accommodating the laundry detergent; then a filling pump on a feeding component injects liquid into the cavity formed by thermoforming the bottom film on the surface of the drum mold; then the top film is attached to the bottom film and sealed, at this time the product is sealed to form a bead shape, and then it is cut into individual laundry beads.

[0003] When producing and packaging laundry beads, it is necessary to fill the liquid laundry detergent into the cavities formed by vacuum thermoforming of the bottom film. In order to improve efficiency, generally multiple cavities are used in the mold to fill the laundry detergent simultaneously. When filling, a filling valve is required to inject the laundry detergent into multiple cavities arranged in a row. After the laundry detergent is injected, the filling stops, and then waits for the cavity in the next position to rotate to the filling position, and then fills the cavities in the next row, so as to intermittently fill the cavities row by row. In order to fill multiple cavities in the same row in the existing filling equipment, a corresponding filling pipe is arranged above each cavity, and the filling pipe uses a filling valve corresponding to the cavity to control the on-off of the filling pipeline. Each filling valve controls the on-off of the filling pipe on one cavity, so as to realize synchronous filling of multiple cavities. However, in this way, each cavity requires a corresponding filling valve, resulting in a large number of filling valves, which are not easy to control and cannot meet the production requirements of high production efficiency.

[0020] It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] It should be noted that all directional indications (such as up-down-left-right-front-back...) in the embodiments of the present utility model are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the attached drawings). If the specific posture changes, the directional indications will also change accordingly. The connection described can be a direct connection or an indirect connection.

[0023] As Figures 1 - 6 shown, a control mechanism for a filling valve of a pearl packaging machine includes a valve body 1. A plurality of valve cavities 11 are provided in the valve body 1. Liquid inlet pipes 12 corresponding to the valve cavities 11 one by one are fixedly connected to the upper end surface of the valve body 1. Liquid outlet pipes 13 corresponding to the valve cavities 11 one by one are fixedly connected to the lower end surface of the valve body 1. The liquid inlet pipes 12 and the liquid outlet pipes 13 are arranged oppositely, and the inner holes of the liquid inlet pipes 12 and the liquid outlet pipes 13 extend into the valve cavities 11. A one-way valve 14 for unidirectionally feeding liquid into the valve cavity 11 is provided in the liquid inlet pipe 12, and a one-way valve 14 for unidirectionally discharging liquid out of the valve cavity 11 is provided in the liquid outlet pipe 13. A first piston head 2 is slidably connected in the valve cavity 11, and the first piston head 2 is in sealing cooperation with the inner wall of the valve cavity 11. A connecting cavity 15 is provided in the valve body 1. The connecting cavity 15 is located at one end of the valve cavity 11 away from the liquid inlet pipe 12 and communicates the plurality of valve cavities 11 in the valve body 1. A transmission block 3 is arranged in the connecting cavity 15. A driving assembly 4 is arranged at one end of the valve body 1 away from the liquid inlet pipe 12. The first piston head 2 is connected to the transmission block 3, and the driving assembly 4 drives the transmission block 3 to move so as to synchronously drive the first piston heads 2 in different valve cavities 11 to move synchronously.

[0024] With the above technical solution, by driving the first piston head 2 to move through the driving assembly 4, the plurality of first piston heads 2 move synchronously, so that the external laundry detergent is sucked into the valve cavity 11 through multiple channels. The first piston head 2 moves to squeeze the laundry detergent, so that the laundry detergent in the valve cavity 11 is discharged from the liquid outlet pipe 13 into the filling pipe and then poured into the mold cavity, so that a filling valve can synchronously fill multiple mold cavities, improving the filling efficiency, reducing the number of filling valves, and making the layout more compact.

[0025] Specifically, a connecting rod 5 is fixedly connected to the first piston head 2. A chute 31 is provided on the transmission block 3. An extension part 51 is arranged at the end of the connecting rod 5. The extension part 51 is located on both sides of the transmission block 3, and a convex part 52 is fixedly connected to the extension part 51. The convex part 52 is located in the chute 31 and is in sliding cooperation with the chute 31. Through the sliding cooperation between the convex part 52 and the chute 31, the transmission block 3 and the connecting rod 5 can slide. When there is a non-parallel error in the axes between the plurality of connecting rods 5, the connecting rod 5 can slide along the transmission block 3, thereby avoiding the deviation between the plurality of connecting rods 5 caused by the rigid connection between the transmission block 3 and the connecting rod 5 and forming jamming, making the driving smoother.

[0026] Specifically, the driving assembly 4 includes a cylinder block 41 connected to the valve body 1. A cylindrical cavity 42 is formed in the cylinder block 41. A second piston head 43 that is slidably engaged with the inner wall of the cylindrical cavity 42 is disposed in the cylindrical cavity 42. A piston rod 44 is fixedly connected to the second piston head 43. The piston rod 44 extends into the valve body 1 and is fixedly connected to the transmission block 3. Air vents 45 communicating with both ends of the cylindrical cavity 42 are respectively disposed at both ends of the cylinder block 41. The air vents 45 are connected to an external air pipe and drive air is inputted to drive the second piston head 43 to move, thereby driving the first piston head 2 to move to fill the washing liquid.

[0027] Specifically, a connection seat 46 is threadedly connected to the cylinder block 41. The connection seat 46 is threadedly connected to the valve body 1. The piston rod 44 passes through the connection seat 46 and the outer wall of the piston rod 44 is sealingly engaged with the connection seat 46. One end of the connection seat 46 away from the connection seat 46 extends into the cylindrical cavity 42 and is fixedly connected with an adjusting block 47. The adjusting block 47 is sleeved outside the piston rod 44. By sleeving the adjusting block 47 on the piston rod 44, the moving distance of the second piston head 43 is limited. By providing adjusting blocks 47 with different thicknesses, the moving stroke of the second piston head 43 is adjusted, and further the liquid injection amount during filling is controlled to adapt to the filling liquid injection of different products.

[0028] Specifically, the valve body 1 is fixed on a mounting plate 6. The mounting plate 6 is fixed on a machine frame 8 through a support plate 7. Multiple layers of mounting plates 6 are provided on the machine frame 8, and multiple valve bodies 1 are mounted on each mounting plate 6. Thus, through multiple grouped arrangements, the same device can fill the cavities on multiple molds.
