Description

Technical Field

[0001] The utility model belongs to the technical field of sanitary napkin packaging, in particular to an equidistant conveying mechanism of a napkin unscrambler. Background Art

[0002] Existing dual-channel sanitary napkin sorting machines typically use the gap between two sets of flat or elastic belts to sort the sanitary napkins into two lanes. A specially designed KK plate and aligning table then move the products from the high-speed linear motion of the sanitary napkin production machine into groups of several sheets, which then move slowly for easy manual removal.

[0003] Currently, a Chinese utility model with publication number CN220350190U discloses a conveying mechanism for a sanitary napkin packaging machine. During the conveying process, the existing dual-channel sanitary napkin sorting machine has uneven loading of sanitary napkins, resulting in inconsistent spacing between sanitary napkins as they move on the conveyor belt. Even if the loading is uniform, sanitary napkins will collide with the equipment during long-term conveyance on the conveyor belt, causing their position to shift, resulting in changes in the spacing between sanitary napkins. This makes it impossible to ensure the front-to-back spacing during the conveyance process, making it inconvenient to effectively distribute and package the sanitary napkins later. This can easily lead to inconsistent quantities of distributed packaging, reducing the packaging efficiency of sanitary napkins. Utility Model Content

[0004] The purpose of the utility model is to provide an equidistant conveying mechanism for a sheet sorting machine, which has the advantage of conveying sanitary napkins at equal intervals, facilitating subsequent distribution and packaging, and adjusting the spacing of the sanitary napkins at equal intervals.

[0005] The above-mentioned technical purpose of the present utility model is achieved through the following technical solutions: an equidistant conveying mechanism of a film sorting machine, comprising a supporting base plate, both sides of the bottom of the supporting base plate are rotatably connected to synchronous wheels, one side of the synchronous wheel is rotatably connected to a barrel seat bolted to the supporting base plate, the side of the barrel seat away from the synchronous wheel is bolted to a driving motor, the output end of the driving motor is bolted to a connecting shaft that is rotatably connected to the inside of the barrel seat, the end of the connecting shaft away from the driving motor is clamped with the inside of the synchronous wheel, the surface transmission sleeve of the synchronous wheel is connected to a synchronous belt, and the surface of the synchronous belt is installed with a block.

[0006] Using this technical solution, the drive motor turns on to rotate the synchronous belt. When the sanitary napkin reaches the top of the synchronous belt, the stopper, driven by the synchronous belt, pushes the sanitary napkin forward at a constant speed. The force of the stopper separates the sanitary napkins and maintains an equal spacing for uniform conveyance. This facilitates subsequent sorting and packaging of the sanitary napkins, improving packaging efficiency. By securing the stopper forward or backward within the retaining grooves at different locations on the synchronous belt surface, and utilizing the magnetic attraction between the metal sheet and the magnet, the spacing between the two stoppers can be increased or decreased. This allows for adjustable delivery spacing of sanitary napkins, allowing for even delivery of sanitary napkins at varying intervals, improving practicality.

[0007] The utility model is further configured as follows: a fixing groove is provided on the surface of the synchronous belt, the interior of the fixing groove is an inverted trapezoid, the stop block is clamped to the surface of the synchronous belt through the fixing groove, a metal sheet fixedly connected to the synchronous belt is provided at the bottom of the inner cavity of the fixing groove, and a magnet block is welded to the bottom of the stop block which is magnetically attracted to the metal sheet.

[0008] By adopting the above technical solution, the size of the sanitary napkin conveying interval is adjusted so that the sanitary napkins can be conveyed at equal distances with different intervals, thereby improving practicality.

[0009] The utility model is further configured as follows: support bars are bolted to both sides of the top of the support base plate.

[0010] The above technical solution is adopted to reduce the friction of sanitary napkins during the equal-interval transportation process and improve the transportation stability.

[0011] The utility model is further configured as follows: a limiting baffle bolted to the supporting base plate is provided on one side of the two support bars away from each other, and an inclined groove is provided on one side of both ends of the limiting baffle close to the supporting base plate.

[0012] By adopting the above technical solution, the two sides of the transported sanitary napkins can be limited to prevent the sanitary napkins from being skewed or offset when being transported at equal intervals.

[0013] The utility model is further configured as follows: connecting plates are bolted to both sides of the bottom of the supporting base plate.

[0014] By adopting the above technical solution, it is convenient to bolt the equally spaced conveying mechanism to the connecting plate through bolts so as to be installed on the sheet handling machine.

[0015] The utility model is further configured as follows: a fixing seat is bolted to the bottom of the supporting base plate, one side of the fixing seat is rotatably connected to a rocker arm, and one end of the rocker arm away from the fixing seat is rotatably connected to a driven wheel used in conjunction with a synchronous belt.

[0016] With the above technical solution, the rocker arm rotates on one side of a fixed seat, causing the driven wheel to swing left and right around the center of the rocker arm. This allows the position to be moved up and down to adjust the tightness of the synchronous belt on the synchronous wheel surface.

[0017] The utility model is further configured as follows: a clamping ring rotatably connected to the connecting shaft is clamped on a side of the synchronous wheel away from the barrel seat.

[0018] By adopting the above technical solution, the stability of the connecting shaft fixedly installed inside the synchronous wheel is improved, thereby ensuring the transmission efficiency.

[0019] In summary, the present invention has the following beneficial effects:

[0020] 1. By turning on the drive motor to drive the synchronous belt, when the sanitary napkin reaches the top of the synchronous belt, the stopper, driven by the synchronous belt, pushes the sanitary napkin forward at a constant speed. Under the force of the stopper, the sanitary napkins are separated and kept at equal distances for uniform conveyance. This facilitates the subsequent sorting and packaging of the sanitary napkins and improves packaging efficiency.

[0021] 2. By locking the blocks forward or backward into the retaining grooves at different locations on the synchronous belt surface, and using the magnetic attraction between the metal sheet and the magnet, the distance between the two blocks can be expanded or reduced. This allows the distance between sanitary napkins to be adjusted, allowing them to be evenly spaced and delivered at different intervals, improving practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present invention will be described in further detail below with reference to the accompanying drawings.

[0027] Example 1, reference Figure 1 、 Figure 2A uniformly spaced conveying mechanism for a sheet sorting machine includes a supporting base plate 1, both sides of the bottom of the supporting base plate 1 are rotatably connected to synchronous wheels 2, one side of the synchronous wheel 2 is rotatably connected to a barrel seat 3 bolted to the supporting base plate 1, the side of the barrel seat 3 away from the synchronous wheel 2 is bolted to a driving motor 4, the output end of the driving motor 4 is bolted to a connecting shaft 5 that passes through and is rotatably connected to the inside of the barrel seat 3, the end of the connecting shaft 5 away from the driving motor 4 is engaged with the inside of the synchronous wheel 2, the surface of the synchronous wheel 2 is connected to a synchronous belt 6, and the surface of the synchronous belt 6 is installed with a stopper 7. The synchronous belt 6 is driven by turning on the driving motor 4 to rotate. When the sanitary napkin is conveyed to the top of the synchronous belt 6, the stopper 7 is driven by the synchronous belt 6 to push the sanitary napkin forward at a uniform speed, so that the sanitary napkin is separated by the force of the stopper 7 and maintained at an equal spacing for uniform conveyance. This facilitates the subsequent sorting and packaging of the sanitary napkins and improves packaging efficiency.

[0028] refer to Figure 1 , both sides of the top of the support base plate 1 are bolted with support strips 11. The friction of the sanitary napkins during the equal-spaced transportation process is reduced, and the transportation stability is improved.

[0029] refer to Figure 1 The two support bars 11 are provided with a limit block 12 bolted to the support base 1 on the side away from each other. The two ends of the limit block 12 are provided with an inclined groove 17 on the side close to the support base 1. The two sides of the transported sanitary napkins can be limited to prevent the sanitary napkins from skewing when being transported at equal intervals.

[0030] refer to Figure 1 The side of the synchronous wheel 2 away from the barrel seat 3 is clamped with a clamping ring 18 that is rotatably connected to the connecting shaft 5. Improve the stability of the connecting shaft 5 being clamped and installed inside the synchronous wheel 2 to ensure transmission efficiency.

[0031] Brief description of the usage process: First, the equal-pitch conveying mechanism is installed at the end of the belt conveyor platform. When the belt conveys sanitary napkins onto the equal-pitch conveying mechanism, the drive motor 4 is turned on to rotate the synchronous pulley 2 via the connecting shaft 5, so that the two synchronous pulleys 2 drive the synchronous belt 6. When the sanitary napkins are conveyed to the top of the synchronous belt 6, the stopper 7 on the surface of the synchronous belt 6 pushes the sanitary napkins forward at a constant speed under the drive of the synchronous belt 6. As a result, the sanitary napkins are separated by the force of the stopper 7 and kept at equal spacing for uniform conveyance.

[0032] Example 2, reference Figure 1 、 Figure 2 、 Figure 3A uniformly spaced conveying mechanism for a sheet unscrambling machine. The surface of a synchronous belt 6 is provided with a securing groove 8. The interior of the securing groove 8 is in the shape of an inverted trapezoid. A stopper 7 is secured to the surface of the synchronous belt 6 via the securing groove 8. A metal sheet 9 fixedly connected to the synchronous belt 6 is provided at the bottom of the inner cavity of the securing groove 8. A magnet 10 is welded to the bottom of the stopper 7 and magnetically attracted to the metal sheet 9. By securing the stopper 7 forward or backward within the securing groove 8 at different positions on the surface of the synchronous belt 6, and utilizing the mutual magnetic attraction between the metal sheet 9 and the magnet 10, the spacing between the two stoppers 7 can be expanded or reduced. This allows the sanitary napkin delivery spacing to be adjusted, allowing sanitary napkins to be delivered at equal distances at different intervals, thereby improving practicality.

[0033] refer to Figure 1 , both sides of the bottom of the supporting base plate 1 are bolted with connecting plates 13. It is convenient to bolt the equal-pitch conveying mechanism to the connecting plates 13 through bolts and thus install it on the sheet processing machine.

[0034] refer to Figure 1 A mounting base 14 is bolted to the bottom of the support base 1. A rocker arm 15 is pivotally connected to one side of the mounting base 14. The end of the rocker arm 15, away from the mounting base 14, is pivotally connected to a driven pulley 16 that cooperates with the timing belt 6. By rotating the rocker arm 15 on a different side of the mounting base 14, the driven pulley 16 swings left and right around the center of the rocker arm 15. This allows the tension of the timing belt 6 on the surface of the timing pulley 2 to be adjusted by moving the rocker arm 15 up and down.

[0035] Brief description of the usage process: By using the trapezoidal retaining groove 8 to secure the stopper 7 to the inside of the synchronous belt 6, and by magnetically attracting the metal sheet 9 and the magnet block 10, the stopper 7 is reinforced and installed, so that the stopper 7 can stably push the sanitary napkin forward. At the same time, by securing the stopper 7 forward or backward in the retaining groove 8 at different positions on the surface of the synchronous belt 6, the distance between the two stoppers 7 can be increased or decreased, thereby adjusting the distance between the sanitary napkins, so that the sanitary napkins can be transported at different intervals.
