Description

Technical Field

[0001] This invention relates to packaging machinery, specifically to a bag feeding mechanism applied to a bag-type packaging machine. Background Technology

[0002] Currently, the packaging bags used in bagging machines are generally divided into three-side seal bags, four-side seal bags, irregularly shaped bags, and M-shaped packaging bags, etc. They are used for packaging granules, seasonings, sauces, and food products. The machine includes a bag feeding mechanism (i.e., bag loading mechanism), a bag clamping mechanism, a bag supporting mechanism, a filling mechanism, a vacuuming mechanism, a heat sealing mechanism, and a power mechanism. The bag feeding mechanism conveys the packaging bags as the large turntable rotates. To improve packaging speed, the large turntable needs to rotate continuously. However, this results in unstable bag feeding and mismatch between the bag feeding mechanism and the parallelism of the large turntable (which is equipped with a vacuum chamber back seat), leading to deviations and inaccuracies in the bag feeding process, thus affecting packaging quality and efficiency. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide a stable and coordinated bag feeding mechanism that enables smooth bag feeding operation and parallelism matching.

[0004] The objective of this invention is achieved through the following technical solution: a smooth and coordinated bag feeding mechanism, comprising a large turntable, a large turntable bearing seat, and a bag feeding device. The bag feeding device consists of a bag feeding cam, a bag feeding lower swing arm, a bag feeding pull rod, a bag feeding transmission assembly, a bag feeding push rod, and a bag feeding upper swing arm connected in sequence. An adjusting slide is installed between the bag feeding push rod and the bag feeding upper swing arm. The adjusting slide is connected to the large turntable bearing seat through a tracking swing arm. A tracking cam is installed on the side of the bag feeding cam. A tracking pull rod is installed on the tracking cam through a tracking swing arm. The tracking pull rod is connected to the tracking push rod through a tracking transmission assembly. The tracking push rod is connected to the tracking swing arm.

[0005] The tracking transmission assembly includes a connected lower tracking push-pull arm, a tracking pull rod seat, and an upper tracking push-pull arm. The lower tracking push-pull arm is connected to the tracking pull rod, and the upper tracking push-pull arm is connected to the tracking push rod. The tracking rotating arm is connected to the large turntable bearing seat via a connecting plate. A fixing clamp is fitted onto the bag feeding upper swing arm via a connecting shaft. A vacuum chamber rear seat is mounted on the large turntable, and the fixing clamp corresponds to the position of the vacuum chamber rear seat. The concave grooves on the bag feeding cam and the tracking cam have corresponding and matching shapes.

[0006] With the adoption of this invention, due to the operation of the bag feeding cam and the tracking cam, the continuous rotation of the large turntable and the large turntable bearing seat drives the tracking arm, the tracking push rod, and the adjusting slide. This causes the connecting bushing and the fixed clamping plate linked with the adjusting slide to change accordingly with the position change of the vacuum chamber rear seat on the large turntable. The horizontal parallelism is matched, the operation is more stable, and the actions are more coordinated. This ensures that the bag feeding and bag loading positions are aligned without deviation and the bag loading is accurate, making full preparation for the next step of vacuuming the material, thereby improving the packaging quality and working efficiency of the bag packaging machine.

[0007] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0010] Reference Figure 1 , Figure 2 It is understood that the present invention is applied to the smooth and coordinated bag feeding mechanism of a bag packaging machine, including a large turntable 1 (equipped with a vacuum chamber rear seat 23), a large turntable bearing seat 2, and a bag feeding device. The bag feeding device consists of a bag feeding cam 3, a bag feeding lower swing arm 4, a bag feeding pull rod 5, a bag feeding transmission assembly (including a connected bag feeding lower push-pull arm 6, a bag feeding pull rod seat 7, and a bag feeding upper push-pull arm 8), a bag feeding push rod 9, and a bag feeding upper swing arm 10 connected in sequence. An adjusting slide 11 is installed between the bag feeding push rod 9 (in the lower position) and the bag feeding upper swing arm 10 (in the upper position). The adjusting slide 11 is connected to the large turntable bearing seat 2 through a tracking rotating arm 12. A tracking cam 13 is installed on the side of the bag feeding cam 3. A tracking pull rod 15 is installed on the tracking cam 13 through a tracking swing arm 14. The tracking pull rod 15 is connected to the tracking push rod 19 through a tracking transmission assembly. The tracking push rod 19 is connected to the tracking rotating arm 12. The bag feeding transmission assembly includes a connected lower bag feeding push-pull arm 6, a bag feeding pull rod seat 7, and an upper bag feeding push-pull arm 8. The lower bag feeding push-pull arm 6 is connected to the bag feeding pull rod 5, and the upper bag feeding push-pull arm 8 is connected to the bag feeding push rod 9.

[0011] The tracking transmission assembly includes a lower tracking push-pull arm 16, a tracking pull rod seat 17, and an upper tracking push-pull arm 18 connected together. The lower tracking push-pull arm 16 is connected to the tracking pull rod 15, and the upper tracking push-pull arm 18 is connected to the tracking push rod 19. The tracking rotating arm 12 is connected to the large turntable bearing seat 2 via a connecting plate 20. A fixing clamp 22 (for clamping the packaging bag) is mounted on the bag feeding upper swing arm 10 via a connecting bushing 21. A vacuum chamber rear seat 23 is mounted on the large turntable 1, and the positions of the fixing clamp 22 and the vacuum chamber rear seat 23 correspond to each other. The concave grooves on the bag feeding cam 3 and the tracking cam 13 have corresponding and matching shapes. The bag feeding lever 5, the bag feeding transmission assembly (including the connected bag feeding lower push-pull arm 6, bag feeding lever seat 7, and bag feeding upper push-pull arm 8), and the bag feeding push rod 9 are respectively matched with the tracking lever 15, the tracking transmission assembly (including the connected tracking lower push-pull arm 16, tracking lever seat 17, and tracking upper push-pull arm 18), and the tracking push rod 19. The positions of the tracking push rod 19 and the tracking rotating arm 12 are slightly higher than the bag feeding push rod 9.

[0012] As shown in the attached figure, the working principle of the present invention is as follows: the bag feeding cam 3, the tracking cam 13, and the large turntable 1 work simultaneously. The bag feeding cam 3 sequentially drives the bag feeding lower swing arm 4, the bag feeding pull rod 5, the bag feeding transmission assembly (including the connected bag feeding lower push-pull arm 6, bag feeding pull rod seat 7, and bag feeding upper push-pull arm 8), the bag feeding push rod 9, the adjusting slide seat 12, and the bag feeding upper swing arm 10 to run. At the same time, the tracking cam 13 sequentially drives the tracking swing arm 14, the tracking pull rod 15, the tracking transmission assembly, and the tracking push rod 19 to run. The continuous rotation of the large turntable 1 and the large turntable bearing seat 2 drives the tracking swing arm 12, the tracking push rod 19, and the adjusting slide seat 11. As a result, the connecting bushing 21 and the fixed clamping plate 22 change accordingly with the position change of the vacuum chamber rear seat 23 on the large turntable. Their conformal tracking operation results in horizontal parallel matching and smoother operation.
