Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, specifically a lapel-type back-sealing packaging machine with adjustable flow rate. Background Technology

[0002] Packaging machines are a type of machine used to package products, serving to protect and enhance their appearance. Packaging machines can be categorized by type, including: liquid packaging machines, powder packaging machines, granule packaging machines, skin packaging machines, sauce packaging machines, electronic combination scale packaging machines, pillow packaging machines, and flip-collar back-seal packaging machines, among others.

[0003] In the field of lapel-type back-seal packaging machines, controlling the material feeding speed is a key factor affecting packaging quality. Traditional packaging machines typically employ a fixed feeding port or a manually adjustable valve design, such as controlling material flow through simple gate opening and closing. However, this design has significant drawbacks: during initial feeding, a large amount of material is instantly poured out due to gravity, resulting in uncontrollable flow velocity and causing severe impact on the packaging bag. This impact can not only cause bag deformation and incomplete sealing but may also lead to material splashing, increased weighing errors, and even damage to the packaging machine's feeding mechanism. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-6In this embodiment of the present invention, a collar-type back-seal packaging machine with flow rate adjustment includes a frame 10, a hopper 20 mounted on the frame 10, and a feeding mechanism 30. A feeding valve 50 is provided between the hopper 20 and the feeding mechanism 30. The hopper 20 is used to store the material to be packaged. In this embodiment, the material is granular or powdered material. The feeding valve 50 is used to discharge the material intermittently to avoid adding too much material at once. A lower housing 40 is provided at the bottom of the feeding mechanism 30. A feeding pipe 41 is connected to the bottom of the lower housing 40. The feeding pipe 41 is used to discharge the material so that the material enters the packaging bag pre-placed in the packaging machine. It should be noted that this embodiment uses a collar-type back-seal packaging machine. The packaging machine and the mechanism for providing the packaging bag in the packaging machine are existing technologies. This application mainly improves the material feeding method, and the packaging of the material after feeding is not described in detail. The feeding mechanism 30 includes an upper housing 31 and a baffle plate 32. The bottom of the upper housing 31 is connected to the lower housing 40 through an opening. The baffle plate 32 is rotatably mounted inside the upper housing 31 via a drive shaft 35. An arc-shaped feeding wall 33 is provided on one inner wall of the upper housing 31. The side of the baffle plate 32 near the arc-shaped feeding wall 33 is circular, and there is a gap between the baffle plate 32 and the arc-shaped feeding wall 33 for material to pass through. After the material falls into the upper housing 31, the baffle plate 32 rotates away from the arc-shaped feeding wall 33, and the gap between the baffle plate 32 and the arc-shaped feeding wall 33 gradually increases. The material flows along the arc-shaped feeding wall 33 towards the opening. It can be understood that in the initial stage of feeding, the small gap between the baffle plate 32 and the arc-shaped feeding wall 33 can avoid material impact caused by a large amount of material feeding. As feeding proceeds, by rotating the baffle plate 32, the gap is increased, promoting the falling of material and realizing the regulation of the material feeding flow rate.

[0022] In this embodiment, the feeding valve 50 includes a feeding pipe 51 and a baffle rod 52. The upper and lower sides of the feeding pipe 51 are respectively connected to the hopper 20 and the feeding mechanism 30. A feeding channel is provided inside the feeding pipe 51. The baffle rod 52 is slidably installed on the feeding pipe 51. A feeding channel that cooperates with the feeding channel is provided on the baffle rod 52. When the feeding channel and the feeding channel are connected, the material falls from the hopper 20 into the feeding mechanism 30. By controlling the sliding of the baffle rod 52, the connection and separation of the feeding channel and the feeding channel can be realized.

[0023] Furthermore, in this embodiment, the upper housing 31 is also equipped with a guide rod 53, a gearbox 54, and a drive motor 55, such as... Figure 2 As shown, multiple guide rods 53 are provided, and the multiple guide rods 53 are symmetrically arranged on both sides of the feed pipe 51. Figure 2There are four guide rods 53, which are symmetrically arranged in pairs on both sides of the feed pipe 51. The side of the baffle rod 52 is provided with a sliding sleeve, which is slidably connected to the guide rod 53. The sliding sleeve is fixedly installed with a rack 56, which meshes with a second gear 545 rotatably mounted on the upper housing 31. The drive motor 55 is connected to the shaft of the second gear 545 through a gearbox 54. The drive motor 55 is used to drive the second gear 545 to rotate through the gearbox 54, and then control the sliding sleeve and the baffle rod 52 to slide through the rack 56.

[0024] Furthermore, in this embodiment of the application, the drive motor 55 is a reversible motor structure. During material feeding, the output end of the drive motor 55 rotates clockwise to connect the feeding channel of the baffle rod 52 with the unloading channel. After material feeding is completed, the output end of the drive motor 55 rotates counterclockwise to separate the feeding channel of the baffle rod 52 from the unloading channel.

[0025] In this embodiment, a first gear 544 is fixedly mounted on one end of the drive shaft 35, and a sector gear 543 is rotatably mounted on the outer side of the upper housing 31. The sector gear 543 meshes with the first gear 544. The drive motor 55 is also connected to the connecting shaft 541 through the gearbox 54. The connecting shaft 541 is connected to the sector gear 543 through the synchronous belt 542.

[0026] Furthermore, in this embodiment, a reset mechanism 36 is provided at the other end of the drive shaft 35. The reset mechanism 36 includes a housing 361 fixedly mounted on the upper housing 31. An arc-shaped cavity is opened inside the housing 361. The drive shaft 35 extends into the interior of the housing 361, and a steering plate 351 is fixedly mounted at one end of the drive shaft 35 inside the housing 361. The steering plate 351 is connected to one side of the arc-shaped cavity through a reset spring 362. It can be understood that the sector gear 543 intermittently controls the rotation of the first gear 544 during rotation. When the first gear 544 rotates, the baffle plate 32 rotates synchronously, and the gap between the baffle plate 32 and the arc-shaped discharge wall 33 increases. When the sector gear 543 separates from the first gear 544, the reset spring 362 controls the drive shaft 35 to reset, and the gap between the baffle plate 32 and the arc-shaped discharge wall 33 decreases.

[0027] Furthermore, in this embodiment, a buffer plate 34 is provided on the side of the baffle plate 32 away from the arc-shaped discharge wall 33. After the material falls into the interior of the upper housing 31, the material drives the baffle plate 32 and the drive shaft 35 to rotate away from the arc-shaped discharge wall 33. After the material is discharged, the reset spring 362 controls the drive shaft 35 and the baffle plate 32 to reset. The buffer plate 34 collides with the inner wall of the upper housing 31, thereby promoting the flow of material and preventing the material from accumulating or adhering to the interior of the upper housing 31. It should also be noted that multiple shock-absorbing springs 42 are provided at the connection between the upper housing 31 and the lower housing 40. The shock-absorbing springs 42 are used to buffer the vibration force.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
