Description

Technical Field

[0001] This utility model relates to the field of supply lines, and in particular to a push rod mechanism for a packaging machine supply line. Background Technology

[0002] When a product is packaged in a pillow-type packaging machine, the product is pushed forward by a pusher on the supply chain of the packaging machine. Through the transmission of the chain, the product slides forward in a set chute to the head of the packaging machine and enters the bag maker, thus completing the product packaging.

[0003] The type of pusher spacing used in packaging production depends on the length of the product. If the product lengths differ by more than double, there are generally two production methods. The first method uses two packaging machines: one with a large-pitch pusher for longer products and one with a small-pitch pusher for shorter products. The second method uses a large-pitch pusher for all products, regardless of length. The first method requires an additional investment in equipment and more factory space, while the second method, which uses a large-pitch pusher to accommodate shorter products, has lower capacity and lower efficiency, thus presenting certain drawbacks.

[0041] 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.

[0042] This utility model provides, for example Figure 1-7 The diagram shows a push rod mechanism for a packaging machine supply line.

[0043] Example 1

[0044] The system includes a conveyor frame 1, a load-bearing track 2, a drive chain belt 3, a first push rod 4, a second push rod 5, and a guide assembly 6. The load-bearing track 2 is mounted on the conveyor frame 1 and is used to carry and guide the products. The drive chain belt 3 is installed inside the conveyor frame 1 and is driven by a drive motor, drive shaft, and gears mounted on the conveyor frame 1. This is existing technology and will not be described in detail here. The first push rod 4 and the second push rod 5 rotate alternately on one side of the drive chain belt 3, and the load-bearing track 2 has slots that match the first push rod 4 and the second push rod 5, so that the first push rod 4 and the second push rod 5 can push the products during operation. The product on the carrying track 2 is fed. The guide assembly 6 is installed on the conveyor frame 1. The guide assembly 6 is used to guide and limit the first push rod 4 and the second push rod 5. The guide assembly 6 is also used to change the working state of the second push rod 5. The first push rod 4 is a normal push rod, and the second push rod 5 is a non-working push rod. That is, under the action of the guide assembly 6, the second push rod 5 can be put into a non-working state, so that the spacing between the products pushed on the carrying track 2 can be increased. That is, when both the first push rod 4 and the second push rod 5 are working, a short pushing station is formed between the first push rod 4 and the second push rod 5. When the second push rod 5 is not working, a long pushing station is formed between two adjacent first push rods 4.

[0045] In particular, the guide assembly 6 includes a guide rail 61, a first guide rod 62, a second guide rod 63, and a switch unit. The guide rail 61 is mounted on the conveyor frame 1. One end of the first guide rod 62 is fixedly connected to the first push rod 4, and one end of the second guide rod 63 is fixedly connected to the second push rod 5. The guide rail 61 is used to guide and limit the first guide rod 62 and the second guide rod 63. When both the first guide rod 62 and the second guide rod 63 slide inside the guide rail 61, the first push rod 4 and the second push rod 5 can be guided and limited, thereby keeping the first push rod 4 and the second push rod 5 in a stable state to push the product. The length of the second guide rod 63 is greater than the length of the first guide rod 62. The switch unit is connected to the conveyor frame 1 and is connected to the guide rail 61. That is, the switch unit can control whether the second guide rod 63 runs in the track.

[0046] Example 2

[0047] Based on Embodiment 1, the switching unit includes a guide housing 64 and a limiting component. One side of the guide housing 64 is fixedly connected to the conveyor frame 1, and the inner cavity of the guide housing 64 is connected to the inner cavity of the guide rail 61. The limiting component is disposed on the guide housing 64 and is used to change the movement trajectory of the second guide rod 63, thereby changing the working state of the second push rod 5.

[0048] In particular, the limiting component includes a triangular block 66 and a slot. A sliding hole corresponding to the triangular block 66 is formed on one side of the guide housing 64. The slot is formed at the bottom of the guide housing 64, corresponding to the triangular block 66. Because the length of the second guide rod 63 is greater than the length of the first guide rod 62, and the width of the triangular block 66 is limited, the triangular block 66 will not guide or limit the first guide rod 62, thus not changing the working state of the first push rod 4. An inclined slope 67 matching the triangular block 66 is formed on one side of the bottom of the guide housing 64. Figure 6 As shown, when the triangular block 66 blocks the slot at the bottom of the guide housing 64, the switch unit is in the closed state, and the second guide rod 63 slides inside the guide housing 64 to the inside of the guide rail 61, thereby ensuring the normal operation of the second push rod 5. Figure 7 As shown, when the triangular block 66 is located at the top of the inner cavity of the guide housing 64, the second guide rod 63 slides along the bottom of the triangular block 66 and the inclined slope 67 to the bottom of the guide housing 64. That is, the second guide rod 63 does not slide inside the guide rail 61, and the second push rod 5 rotates and tilts, so as not to transport the product on the carrying track 2.

[0049] Specifically, the limiting component also includes a transmission plate 68 and a drive cylinder 69. One side of the transmission plate 68 is fixedly connected to the triangular block 66. The drive cylinder 69 is mounted on the conveyor frame 1. The output end of the drive cylinder 69 is connected to the transmission plate 68. The drive cylinder 69 can drive the triangular block 66 to slide up and down through the transmission plate 68, thereby changing the working state of the switching unit.

[0050] Furthermore, the guide assembly 6 also includes a mounting groove and a strong magnet 65. The mounting groove is formed at the top of the inner wall of the guide housing 64, and the strong magnet 65 is fixedly installed inside the mounting groove. The bottom of the strong magnet 65 is parallel to the top of the inner wall of the guide housing 64, and the first guide rod 62 is made of metal iron. Thus, when the switch unit is in the open state, the slot is in the open state, and the strong magnet 65 can give the first guide rod 62 an upward attraction, thereby preventing the first guide rod 62 from sliding out of the slot and causing the first push rod 4 to not work. When the switch unit is in the open state, the triangular block 66 can guide the second guide rod 63, causing the second guide rod 63 to move away from the strong magnet 65.

[0051] Specifically, it also includes a first shaft and a second shaft. One end of the first shaft is fixedly connected to the transmission chain belt 3, and the outer wall of the first shaft is rotatably connected to the first push rod 4 and the second push rod 5, thereby ensuring the stability of the rotatable connection between the first push rod 4 and the second push rod 5. One end of the second shaft is fixedly connected to the transmission chain belt 3, and the second shaft is used to limit the movement of the first push rod 4 and the second push rod 5, such as... Figure 2 As shown, when the first push rod 4 and the second push rod 5 are located below the transmission chain belt 3, the second shaft can limit the first push rod 4 and the second push rod 5 so that the first guide rod 62 on the first push rod 4 and the second guide rod 63 on the second push rod 5 can slide more accurately into the guide rail 61. This is existing technology and will not be described in detail here.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
