Description

Technical Field

[0001] This utility model relates to the technical field of sheet sorting mechanisms for packaging machines, specifically a sheet sorting mechanism for a nursing pad packaging machine. Background Technology

[0002] In the nursing pad manufacturing industry, nursing pads need to be sorted and stacked by a sorting mechanism before packaging to ensure the smooth progress of subsequent packaging processes. Currently, most nursing pad packaging machines on the market use a material tray combined with a conveyor belt for sorting. During the stacking process, the falling position of the items is prone to deviation, resulting in unstable stacking. Moreover, it is difficult to flexibly adjust the thickness of each stack of items for items of different thicknesses. At the same time, since the material tray is mostly a single-sided fixed structure and the structural design of the mechanism is not flexible enough, it lacks an adjustable guiding and support mechanism. When handling smaller items, the items are prone to fall on the suspended end of the material tray, causing the suspended end to be damaged due to prolonged stress. Furthermore, for larger materials, the support points of the material tray in the existing sorting mechanism are not reasonably distributed, resulting in poor stability when receiving them.

[0003] Therefore, a sheet handling mechanism for a nursing pad packaging machine is proposed to solve the problems mentioned above. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a sheet-sorting mechanism for a nursing pad packaging machine. It utilizes two opposing synchronous belt assemblies and servo motors to drive four synchronous belts. The rotation speed can be adjusted according to the thickness of the nursing pad and its falling speed, ensuring a fixed stacking position for each item and achieving stable stacking. Simultaneously, the thickness of each stack can be flexibly adjusted. A diversion component guides smaller items to the fixed ends of the support plates and synchronous belts, preventing damage to the suspended ends of the support plates due to prolonged stress. Controlling the servo motor of one synchronous belt assembly aligns the second support plate with the first support plate on the other side, ensuring the support points of the two support plates are diagonally distributed. This solves the problems mentioned in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a base, a diversion assembly, and a synchronous belt assembly. The synchronous belt assembly is fixedly installed to the base via a support. Two synchronous belt assemblies are arranged opposite to each other. Each synchronous belt assembly includes a first synchronous belt, a second synchronous belt, a mounting plate, and two servo motors. The two servo motors are respectively used to drive the first and second synchronous belts to rotate. Two first material support plates are fixedly connected to the outer surface of the first synchronous belt, and two second material support plates are fixedly connected to the outer surface of the second synchronous belt. The diversion assembly includes a first plate, a second plate, a flexible connecting piece, and a first telescopic rod.

[0006] Preferably, one end of the flexible connecting piece is fixedly connected to the first plate, and the other end of the flexible connecting piece is fixedly connected to the second plate.

[0007] Preferably, connecting plates are fixedly connected to both sides of the first plate, one end of the first telescopic rod is fixedly connected to the connecting plate, and the other end of the first telescopic rod is connected to a frame.

[0008] Preferably, the connecting plate is slidably connected to the inner surface of the frame, the second plate has a first elongated hole on its side, and the frame has a second elongated hole horizontally on its side.

[0009] Preferably, an adjusting rod is provided inside the first elongated hole, the adjusting rod passes through the second elongated hole, and a second telescopic rod is fixedly connected to the outer side of the frame, with the other end of the second telescopic rod being fixedly connected to the adjusting rod.

[0010] Preferably, the base is fixedly connected to a third telescopic rod, and the other end of the third telescopic rod is connected to the frame.

[0011] Preferably, the servo motor is fixedly mounted on one side of the mounting plate, and the output shaft of the servo motor is fixedly connected to a transmission shaft. The outer side of the transmission shaft is fitted with an active synchronizing wheel and a driven synchronizing wheel.

[0012] Preferably, the driving synchronizing pulley is fixedly connected to the outer side of the transmission shaft, and the driven synchronizing pulley is rotatably connected to the outer side of the transmission shaft via a bearing.

[0013] Compared with the prior art, this utility model provides a sheet handling mechanism for a nursing pad packaging machine, which has the following beneficial effects:

[0014] 1. By using two oppositely arranged synchronous belt assemblies and four servo motors to drive four synchronous belts respectively, the synchronous belt speed can be precisely adjusted according to the thickness and falling speed of the nursing pad, ensuring that the stacked items are in a fixed position each time, achieving stable stacking. At the same time, the thickness of each stack of items can be flexibly adjusted, effectively solving the problems of unstable stacking and inflexible thickness adjustment in existing mechanisms.

[0015] 2. By utilizing the No. 1 and No. 2 plates of the diversion component, the flexible connecting piece, and the No. 1 and No. 2 telescopic rods, the smaller nursing pads are guided to the fixed end of the material support plate and the synchronous belt by adjusting the position of the No. 1 plate and the tilt direction and angle of the No. 2 plate. This prevents the suspended end of the material support plate from being damaged due to long-term stress, extends the service life of the material support plate, and ensures the stability of small material receiving.

[0016] 3. The flow distribution mechanism is driven to slide towards the base by the No. 3 telescopic rod on the base, which allows larger materials to fall directly onto the material support plate. At the same time, the servo motor of the synchronous belt assembly on one side is controlled to rotate, so that the No. 2 material support plate of the No. 2 synchronous belt on that side is aligned with the No. 1 material support plate on the other side, forming diagonally distributed support points, which improves the stability when receiving larger materials and meets the needs of sorting nursing pads of different sizes.

Detailed Implementation

[0025] 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. Example

[0026] Please see Figure 1 - Figure 6The nursing pad packaging machine of this embodiment has a sheet handling mechanism, including a base 1, a diversion component 2 and a synchronous belt component 3. The synchronous belt component 3 is fixedly installed on the base 1 by a support. The two synchronous belt components 3 are arranged opposite to each other. The synchronous belt component 3 includes a first synchronous belt 301, a second synchronous belt 302, a mounting plate 303 and two servo motors 304. The two servo motors 304 are used to drive the first synchronous belt 301 and the second synchronous belt 302 to rotate respectively. Two first material support plates 4 are fixedly connected to the outer surface of the first synchronous belt 301, and two second material support plates 5 are fixedly connected to the outer surface of the second synchronous belt 302. One side of the material support plate is fixedly connected to the synchronous belt, and the other side is suspended.

[0027] The diversion assembly 2 includes a first plate 201, a second plate 202, a flexible connecting piece 203, and a first telescopic rod 204. One end of the flexible connecting piece 203 is fixedly connected to the first plate 201, and the other end of the flexible connecting piece 203 is fixedly connected to the second plate 202. Connecting plates 6 are fixedly connected to both sides of the first plate 201. One end of the first telescopic rod 204 is fixedly connected to the connecting plate 6, and the other end of the first telescopic rod 204 is connected to a frame 7. The connecting plate 6 is slidably connected to the inner surface of the frame 7. A first elongated hole 8 is opened on the side of the second plate 202, and a second elongated hole 9 is horizontally opened on the side of the frame 7. An adjusting rod 10 is provided in the first elongated hole 8, and the adjusting rod 10 passes through the second elongated hole 9. A second telescopic rod 11 is fixedly connected to the outer side of the frame 7 through hole 9. The other end of the second telescopic rod 11 is fixedly connected to the adjusting rod 10. When the second telescopic rod 11 extends or retracts, it drives the adjusting rod 10 to slide along the second long hole 9. One end of the adjusting rod 10 is inside the first long hole 8, thereby changing the tilt direction and angle of the second plate 202. When the first telescopic rod 204 extends or retracts, it changes the position of the first plate 201 according to the size of the material to be sorted and the falling position of the material. A third telescopic rod 12 is fixedly connected to the base 1. The other end of the third telescopic rod 12 is connected to the frame 7. The third telescopic rod 12 can drive the diversion mechanism to slide towards the base 1, so that the material falls directly onto the material support plate.

[0028] The servo motor 304 is fixedly mounted on one side of the mounting plate 303. The output shaft of the servo motor 304 is fixedly connected to the drive shaft 13. The outer side of the drive shaft 13 is fitted with an active synchronous pulley 14 and a driven synchronous pulley 15. The active synchronous pulley 14 is fixedly connected to the outer side of the drive shaft 13, and the driven synchronous pulley 15 is rotatably connected to the outer side of the drive shaft 13 through a bearing. When the servo motor 304 is working, the drive shaft 13 drives the active synchronous pulley 14 to rotate, thereby driving the synchronous belt to rotate. The driven synchronous pulley 15 helps to maintain the stability of the synchronous belt transmission.

[0029] The nursing pads enter from above the sorting mechanism. The two opposing synchronous belt assemblies 3 have a total of four synchronous belts, each driven by a servo motor 304. When the items fall onto the first support plate 4, the servo motor 304 controls the first synchronous belt 301 to rotate slowly. The speed is adjusted according to the thickness of the items and the falling speed. For example, if the thickness of the items is two centimeters, the previous item will fall two centimeters when the next item falls, so that the stacked position of the items is fixed each time, thus achieving stable stacking. At the same time, the second synchronous belt 302 accelerates its rotation. Among the two second support plates 5 connected to the second synchronous belt 302, the inner support plate has a stack of sorted items. When it accelerates its rotation, it sends this stack of items out of the sorting mechanism, while the outer support plate accelerates its upward rotation. When it reaches the top, it receives the falling items. At this time, the first support plate 4 has a stack of sorted items. The thickness of each stack of items can be flexibly adjusted by controlling the speed of the synchronous belts through the servo motor 304.

[0030] When sorting smaller items, the diversion component 2 guides the items, and the first telescopic rod 204 extends and retracts to change the position of the first plate 201. In conjunction with the second telescopic rod 11, the adjusting rod 10 slides along the second elongated hole 9 to change the tilt direction and angle of the second plate 202. Then, through the flexible transition of the soft connecting piece 203, the items are guided to the fixed end of the lifting plate and the synchronous belt, avoiding the lifting plate being subjected to force for a long time, and further achieving the effect of protecting the lifting plate and stably supporting small materials.

[0031] When handling larger materials, the third telescopic rod 12, which is fixedly connected to the base 1, drives the diversion mechanism to slide towards the base 1, allowing the material to fall directly onto the support plate. At the same time, the servo motor 304 of the synchronous belt assembly 3 on one side is controlled to rotate, so that the second support plate 5 of the second synchronous belt 302 on that side is aligned with the first support plate 4 on the other side, making the support points of the two support plates diagonally distributed, thus making it more stable when receiving larger materials. Finally, the care pad falls from below the material handling mechanism, and an external conveying track can be set at its lower end to receive the falling care pad.

[0032] The working principle of the above embodiment is as follows: the servo motor 304 drives the synchronous belt to rotate through the transmission shaft 13 and the active synchronous pulley 14, and the driven synchronous pulley 15 assists in stabilizing the transmission. In the diversion component 2, the first telescopic rod 204 adjusts the position of the first plate 201, the second telescopic rod 11 changes the tilt angle of the second plate 202 through the adjusting rod 10, and the third telescopic rod 12 controls the overall displacement of the diversion component 2 to achieve adaptation to materials of different specifications. In use, the nursing pad enters from the top, is stacked and sorted by the synchronous belt component 3, and then falls from the bottom. Small materials are guided by the diversion component 2 to the fixed end of the support plate, and large materials fall directly to the support plate. After stacking, they are sent to the lower end by the synchronous belt.

[0033] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.
