[0002] The limit mechanism of a packaging machine is a device used to control the range of mechanical movement, and is commonly used in automatic packaging machines, carton sealing machines and other equipment in the packaging industry. When the processed products are packaged, when the conveyor belt drives the products to the predetermined position, the limit sensor will detect the products and send a signal to the control circuit to stop the conveyor belt and perform packaging operations on the products. Since the transmission of the signal requires processing time, there will be a short interval between the sensor detecting the product and the packaging equipment performing the packaging operation. During this period of time, the product may be driven by the electric conveyor belt to continue to move, so that the position of the product changes, resulting in poor packaging quality. In view of this, the utility model proposes a limit mechanism for a packaging machine. Utility Model Content

[0029] Example

[0030] like Figure 1 As shown, a packaging machinery limiting mechanism proposed by the utility model is arranged on an electric conveyor belt 1, and the electric conveyor belt 1 is used to convey products, so as to facilitate moving them to the packaging position for packaging operation. A packaging module is also arranged above the electric conveyor belt 1 for packaging products. It includes two groups of adjustment components 2 for straightening products, and the two groups of adjustment components 2 are symmetrically installed on both sides of the electric conveyor belt 1. The adjustment components 2 include mounting plates 21, first push rod motors 22, and extrusion pads 23. The two groups of mounting plates 21 are symmetrically installed on both sides of the electric conveyor belt 1, and the position of the mounting plates 21 is fixed. The mounting plate 21 is L-shaped, and two groups of first push rod motors 22 are installed on the top of each group of mounting plates 21. The output end of each group of first push rod motors 22 faces one side of the electric conveyor belt 1. The first push rod motor 22 is used to close the output end to the product after extension. Since the extension lengths of the four groups of first push rod motors 22 are the same, the position of the product can be adjusted so that the product is in the middle position without tilting, which is convenient for packaging. The squeezing pad 23 is installed at the output end of the first push rod motor 22 to prevent the first push rod motor 22 from damaging the product surface after extension. Multiple groups of photoelectric sensors 11 are installed on the side of the mounting plate 21 close to each other, and the photoelectric sensors 11 are used to sense whether the product has reached the vicinity of the predetermined position.

[0031] For details, please refer to Figure 3The above-mentioned limiting mechanism includes two groups of moving components 3 respectively installed on the two groups of adjustment components 2 for limiting the position of the product. The moving component 3 includes a second push rod motor 31, a moving plate 32, a connecting rod 33, and a push plate 34. The two groups of second push rod motors 31 are installed on the side of the mounting plate 21, and the position of the second push rod motor 31 is fixed. The moving plate 32 is fixedly connected to the output end of the second push rod motor 31, and the second push rod motor 31 drives the moving plate 32 to move synchronously after starting. The connecting rod 33 is rotatably connected to the side of the moving plate 32 away from the second push rod motor 31, and the push plate 34 is fixedly connected to the end of the connecting rod 33 away from the moving plate 32. The push plate 34 is rotatably connected to the side of the moving plate 32 through the connecting rod 33. After the push plate 34 is rotated to the top of the electric conveyor belt 1, the second push rod motor 31 is started to drive the push plate 34 to move to push and position the product, so that the positioning of the product is accurate.

[0032] Further, such as Figure 1-3As shown, the above-mentioned limiting mechanism also includes a contact component 4 that cooperates with the moving component 3 to position the product before packaging. The contact component 4 includes a moving rod 41, a moving cylinder 42, a synchronization rod 43, a fixed sleeve 44, and a bearing seat 45. The two groups of moving rods 41 are respectively rotatably connected to the two groups of moving plates 32, and the moving plates 32 simultaneously drive the moving rods 41 to move when moving. The moving rod 41 is inserted into the moving plate 32, and the two groups of moving cylinders 42 are respectively fixedly connected to the opposite ends of the two groups of moving rods 41, and the moving cylinder 42 moves synchronously with the moving rod 41. The synchronization rod 43 is slidably connected to the two groups of moving cylinders 42, and the synchronization rod 43 is set in a quadrangular prism shape. When the synchronization rod 43 rotates, it can drive the two groups of moving cylinders 42 to rotate synchronously. Two sets of fixed sleeves 44 are fixedly connected to the synchronization rod 43. The fixed sleeves 44 are rotatably connected to the bearing seat 45 installed on the side of the mounting plate 21. The arrangement of the fixed sleeves 44 and the bearing seat 45 allows the synchronization rod 43 to rotate in place. At the same time, the moving plate 32 is limited by the moving cylinder 42 and the synchronization rod 43 when moving and moves smoothly. The contact assembly 4 also includes a first gear 46 and a second gear 47. The first gear 46 is installed on the outer ring of the connecting rod 33, and the first gear 46 rotates synchronously with the connecting rod 33. The second gear 47 is fixedly connected to the end of the moving rod 41 away from the moving cylinder 42, and the second gear 47 rotates synchronously with the moving rod 41. The first gear 46 is meshed with the second gear 47, and the second gear 47 drives the first gear 46 to rotate synchronously when rotating. The contact assembly 4 also includes a third gear 48 and a fourth gear 49. The third gear 48 is fixedly connected to the outer ring of the synchronization rod 43, and the third gear 48 is arranged at the middle position of the synchronization rod 43. The third gear 48 drives the synchronization rod 43 to rotate synchronously when rotating. A servo motor 5 is also mounted on the side of the mounting plate 21. The output end of the servo motor 5 is fixedly connected to the fourth gear 49. After the servo motor 5 is started, it drives the fourth gear 49 to rotate. The third gear 48 is meshed with the fourth gear 49. When the fourth gear 49 rotates, it drives the third gear 48 to rotate synchronously, thereby realizing the rotation of the synchronization rod 43.

[0033] In this embodiment, first, when the product is conveyed to the position of the photoelectric sensor 11 through the electric conveyor belt 1, the photoelectric sensor 11 senses that the product is between the two groups of mounting plates 21. At this time, the multiple groups of second push rod motors 31 are all started to extend, driving the moving plate 32 to move. At this time, the moving plate 32 moves smoothly under the limiting action of the moving cylinder 42 and the synchronization rod 43, and at the same time drives the push plate 34 to move in the direction away from the mounting plate 21. Then the servo motor 5 is started, and the servo motor 5 drives the fourth gear 49 to rotate and mesh with the third gear 48. At this time, the third gear 48 starts to drive the synchronization rod 43 to rotate, and at the same time, the moving cylinder 42 rotates when the synchronization rod 43 rotates. When the moving cylinder 42 rotates, the second gear 47 is driven to rotate synchronously through the moving rod 41, and the first gear 46 meshed with the second gear 47 starts to rotate, and drives the push plate 34 to rotate through the connecting rod 33. At this time, the push plate 34 rotates to the top of the electric conveyor belt 1, and at this time, the four groups of push plates 34 are all located on the side of the product. Start multiple sets of first push rod motors 22 to extend a fixed length at the same time, so that the squeeze pad 23 contacts the product and aligns the direction of the product. Start multiple sets of second push rod motors 31 to shrink synchronously, so that multiple sets of push plates 34 approach the product synchronously and contact the side of the product. At this time, the position of the product can be adjusted according to the size of the product, and multiple sets of second push rod motors 31 can be started synchronously to drive the product to move and change its position, so that the product is accurately positioned, which is convenient for packaging operations through packaging equipment.

[0034] The above specific embodiment is only an optional embodiment of the present invention.
