Description

Technical Field

[0001] The utility model belongs to the technical field of PPR pipe fitting production and packaging, and in particular relates to a pipe fitting product leveling device that is compatible with two specifications of cartons and can quickly switch. Background Art

[0002] During the automated production and packaging process of PPR pipe fittings, a fixed number of pipe fittings need to be bagged to form bagged pipe fittings, which are then boxed and sealed. Since a large amount of air remains inside the bagged pipe fittings during the bagging process, there are relatively large gaps between the bagged pipe fittings after they are boxed. Before sealing the box, the bagged pipe fittings in the packaging box need to be leveled to expel the air inside and between the bagged pipe fittings, thereby preventing bulging during subsequent box sealing and improving packaging quality. However, since packaging cartons come in two sizes, small and large, and there are significant differences in length, width, and height, the existing manual switching process requires replacing the entire leveling block and adjusting its height. This is difficult to operate and takes a long time to replace. Furthermore, if the replacement and installation are not in place, the carton can easily be crushed during production, affecting product quality. Utility Model Content

[0023] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of the present invention's quick-switch pipe product leveling device compatible with two specifications of cartons, in conjunction with the accompanying drawings.

[0024] like Figure 1 As shown, the present invention provides a quick-switch tubular product leveling device compatible with two sizes of cartons. The device comprises a main frame 1, a roller conveyor 2, a leveling mechanism 3, an adjustable guide and limit mechanism 4, and a sensor 5. The roller conveyor 2 is fixedly mounted in the center of the main frame 1, while the leveling mechanism 3 is mounted above the main frame 1. The adjustable guide and limit mechanisms 4 and the sensor 5 are mounted on either side of the roller conveyor 2. The roller conveyor 2 is used to convey packaging boxes (including large boxes 6 and small boxes 7). The adjustable guide and limit mechanism 4 is used to limit and fix the packaging boxes according to their width. The sensor 5 is used to detect the arrival signal of the packaging boxes. The leveling mechanism 3 is used to press downward to level the bagged tubular products within the packaging boxes. The leveling mechanism 3 includes a leveling cylinder 31, a switching cylinder 32, a small-box leveling block 33, and a large-box quick-switch block 34. The switching cylinder 32 is fixedly mounted above the main frame 1. Its output end is fixedly connected to the upper end of the leveling cylinder 31, allowing it to adjust its height according to the height of the packaging boxes. The small box leveling block 33 is fixedly connected to the output end of the leveling cylinder 31 and is used to level the small box 7. The large box quick switching block 34 is detachably connected to the small box leveling block 33 and is used to level the large box 6.

[0025] The roller conveyor 2 is an existing equipment, which mainly includes an overall frame, feet, rubber-coated rollers, conveying motors, chains, sprockets, etc. The rollers are rubber-coated rollers to ensure that there is sufficient friction between the cartons when conveying them, ensuring the stability of the carton conveying.

[0026] like Figure 2As shown, the adjustable guide limit mechanism 4 includes a front adjustable guide limit plate 41 and a rear adjustable guide limit plate 42. The front and rear adjustable guide limit plates 41 and 42 have adjustable waist-shaped holes on their outer sides. Both are covered with a layer of polytetrafluoroethylene sheet on their inner sides to reduce friction between the plates and the cartons and improve the stability of the guide limit. The front and rear adjustable guide limit plates 41 and 42 are connected to the roller conveyor 2 via two fixed handles 43. When the fixed handles 43 are released, the front adjustable guide limit plate 41 can move forward and backward on the roller conveyor 2 via the waist-shaped holes, thereby accommodating the guide limit of large and small boxes.

[0027] like Figure 3 As shown, the sensing device 5 includes a photoelectric switch fixing frame 51, a photoelectric switch 52, and a photoelectric switch reflecting plate 53. The photoelectric switch fixing frame 51 is fixedly mounted on one side of the roller conveyor 2, the photoelectric switch 52 is fixedly mounted on the photoelectric switch fixing frame 51, and the photoelectric switch reflecting plate 53 is fixedly mounted on the roller conveyor 2 on the opposite side of the photoelectric switch 52. The photoelectric switch 52 is used in conjunction with the photoelectric switch transmitting plate 53 to detect the position of the carton and thereby control the stop of the roller conveyor 2 to ensure that the left and right positions of the carton are uniform.

[0028] like Figure 4 As shown, the leveling mechanism 3 also includes a switching cylinder fixing frame 35, a leveling cylinder fixing plate 36, and a small box leveling pressure block fixing plate 39. The switching cylinder fixing frame 35 is fixedly mounted above the overall frame 1, the switching cylinder 32 is fixedly mounted on the switching cylinder fixing frame 35, the leveling cylinder fixing plate 36 is fixedly connected to the movable block of the switching cylinder 32, and the leveling cylinder 31 is fixedly mounted on the leveling cylinder fixing plate 36. A left switching limit rib 37 and a right switching limit rib 38 are fixedly mounted on both sides of the switching cylinder fixing frame 35. The left switching limit rib 37 and the right switching limit rib 38 limit the left and right sides of the leveling cylinder fixing plate 36 to prevent it from deviating to the left or right, ensure the smooth up and down movement of the leveling cylinder fixing plate 36, and improve the stability of the switching of the switching cylinder 32.

[0029] The small box leveling pressing block fixing plate 39 is connected and fixed with the movable block of the leveling cylinder 31 by 4 hexagon socket screws. The small box leveling pressing block 33 is fixedly connected with the small box leveling pressing block fixing plate 39.

[0030] like Figure 5 As shown, a quick switching groove 331 is respectively provided on the front and rear sides of the small box leveling block 33. Figure 6As shown, two quick-switch bosses 341 are mounted on either side of the inner side of the large-box quick-switch pressing block 34. The large-box quick-switch pressing block 34 is securely connected to the small-box leveling pressing block 33 via a latch 40 and side screws. By loosening the latch 40, the large-box quick-switch pressing block 34 can be withdrawn from the small-box leveling pressing block 33, switching to the small-box leveling mode. Conversely, the large-box quick-switch pressing block 34 can be inserted onto the small-box leveling pressing block 44 and the latch 40 locked to switch to the large-box leveling mode. During this process, the quick-switch bosses 341 and the quick-switch grooves 331 provide guidance for the separation of the two and limit their position, preventing them from shifting vertically.

[0031] The main working mode of this device is to combine the set switching cylinder, switching cylinder fixing frame, leveling cylinder fixing plate, leveling cylinder, etc., and fix the leveling cylinder fixing plate on the movable block of the switching cylinder and move up and down driven by the switching cylinder to form a highly practical leveling device for pipe products that is compatible with two specifications of cartons and can quickly switch.

[0032] The specific implementation process of the utility model device during production is as follows: When automatically packaging large cartons, the large carton quick-switch block 34 is assembled onto the small carton leveling block 33 via the quick-switch groove 331 and the quick-switch boss 341, and then the two are secured together by fastening the buckle 40. The fixing handle 43 is then released, and the front and rear adjustable guide stop plates 41 and 42 are adjusted to ensure that the large carton 6 is centered in the roller conveyor 2 in the front-to-back direction. The fixing handle 43 is then tightened. The system is then switched to large carton production mode and the device is started. The roller conveyor 2 begins operation, conveying the large carton 6 with bagged tubular products from the right end to the left. When the photoelectric switch 52 and the photoelectric switch reflector 53 detect the large carton 6 with bagged tubular products, the roller conveyor 2 stops. At this point, the large carton 6 with bagged tubular products is directly below the assembly of the small carton leveling block 33 and the large carton quick-switch block 34. The leveling cylinder 31 then drives the small box leveling block 33 and the large box quick-switching block 34 assembly to press down several times to expel the air from inside and between the bagged tubes. The leveling cylinder 31 then returns to its original position, and the roller conveyor 2 starts to convey the leveled large box 6 with bagged tube products to the left to the next sealing mechanism for sealing. The device waits for the arrival of the next large box with bagged tube products that needs to be leveled. When the carton produced by automatic packaging is a small box 7, the buckle 40 is opened, and the large box quick-switching block 34 is separated from the small box leveling block 33. The fixed handle 43 is then released, and the front and rear adjustable guide limit plates 41 and 42 are adjusted to ensure that the small box 7 is located in the center of the roller conveyor 2 in the front-to-back direction, and the fixed handle 43 is then locked. The system is then switched to small box production mode and the device is started. Because small boxes are shorter than large boxes, the switching cylinder 32 in small box production mode drives the leveling cylinder fixing plate 36 and the upper leveling cylinder 31 downward. This state is maintained throughout the production of small boxes. Roller conveyor 2 then begins operating, conveying the small box 7 of bagged tubular products, which is being transported from the right end, to the left. When the photoelectric switch 52 and the photoelectric switch reflector 53 detect the small box 7 of bagged tubular products, roller conveyor 2 stops. At this point, the small box 7 of bagged tubular products is directly below the small box leveling block 33. The leveling cylinder 31 then drives the small box leveling block 33 downward several times to expel the air inside and between the bagged tubular products. After the leveling cylinder 31 returns to its original position, roller conveyor 2 activates, conveying the leveled small box 7 of bagged tubular products to the left to the next sealing mechanism for sealing. The device then waits for the arrival of the next small box of bagged tubular products to be leveled. This reciprocating cycle completes the device's operation.
