[0025] The following description of the present invention, with reference to the accompanying drawings, is provided to facilitate a more comprehensive understanding of the various embodiments of the present invention as defined in the claims and their equivalents. The description includes various specific details to assist understanding, but these details should be construed as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the various embodiments described herein without departing from the scope and spirit of the present invention.

[0026] In the description of the present invention, descriptions of directions, such as up, down, front, back, left, right, etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as a limitation on the present invention.

[0027] It will be understood that when one element (e.g., a first element) is “connected” to another element (e.g., a second element), the element may be directly connected to the other element or an intervening element (e.g., a third element) may be present between the element and the other element.

[0028] The embodiment of the present utility model provides a sanitary napkin conveying device, such as Figure 1-5 Shown, including:

[0029] A transmission component 100 is provided with a plurality of levers 110 at intervals. A sanitary napkin accommodating space 120 is formed between the levers 110. A feeding station 130 and a discharging station 140 are provided on the moving path of the levers 110. The lever 110 at the discharging station 140 has a stationary state and a moving state.

[0030] A first transmission wheel 200, one end of the transmission component 100 is sleeved on the first transmission wheel 200;

[0031] The second transmission wheel 300, the other end of the transmission component 100 is sleeved on the second transmission wheel 300, and the first transmission wheel 200 and the second transmission wheel 300 are used to drive the transmission component 100 to rotate;

[0032] The displacement assembly 400 is used to drive the first transmission wheel 200 and the second transmission wheel 300 to move. When the number of sanitary napkins moved to the discharge station 140 reaches a preset number, the lever 110 located at the discharge station 140 is in a stationary state; when the sanitary napkins at the discharge station 140 are taken out, the lever 110 located at the discharge station 140 is in a moving state.

[0033] The transmission component 100 is spaced apart with multiple levers 110. These levers 110 form a space between them for sanitary napkins to be placed between. The transmission component 100 is designed with an infeed station 130 and a discharge station 140 for the entry and exit of sanitary napkins. The levers 110 are spaced apart on the transmission component 100. The levers 110 located at the discharge station 140 have both a stationary state and a movable state. To remove a sanitary napkin from the discharge station 140, the levers 110 at the discharge station 140 remain stationary. To move a sanitary napkin to the discharge station 140, the levers 110 at the discharge station 140 enter a movable state. The transmission component 100 is sleeved onto a first transmission wheel 200 and a second transmission wheel 300, which work together to rotate the transmission component 100. The first and second transmission wheels 200 and 300 drive the rotation of the transmission component 100, thereby conveying sanitary napkins. The displacement assembly 400 is used to drive the first transmission wheel 200 and the second transmission wheel 300 to move. When the discharge station 140 reaches a preset number of sanitary napkins, under the joint action of the displacement assembly 400, the first transmission wheel 200 and the second transmission wheel 300, the lever 110 located at the discharge station 140 remains stationary so that the sanitary napkins can be taken out. At this time, the lever 110 outside the discharge station 140 still remains in a moving state, so that the sanitary napkins can enter the sanitary napkin accommodating space 120 in turn; after the sanitary napkins at the discharge station 140 are moved out of the conveying device of the present invention, the lever 110 at the discharge station 140 and the lever 110 outside the discharge station 140 both remain in a moving state, so that the sanitary napkins can continue to fill the discharge station 140 to be removed in the next round. This device can simultaneously remove a specific number of batches of sanitary napkins from the conveying device while conveying a single sanitary napkin, thereby realizing automatic conveying of sanitary napkins, ensuring a continuous supply of sanitary napkins, improving efficiency and reducing manual operations.

[0034] The transmission component 100 can be implemented in the following ways:

[0035] Ball screw: Used to precisely control the movement of the transmission component 100, achieving accurate delivery of sanitary napkins. Ball screws provide high-efficiency and high-precision transmission and are suitable for applications requiring precise control.

[0036] Gears and chains: These are used to transmit power and motion, achieving mechanical connections and motion transfer between different components. Spur gears, helical gears, or worm gears can be used, with the gear type selected based on the needs.

[0037] Belt drive: Such as synchronous belt drive, which has precise transmission and no-slip characteristics, and is suitable for occasions requiring high-precision positioning and synchronous transmission.

[0038] The displacement assembly 400 can be implemented in the following manner:

[0039] Servo motor: As a power output, it precisely controls the speed and position of the motor to achieve precise movement of the transmission component 100. The servo motor can quickly respond to control signals and achieve precise position control.

[0040] Cylinder: In the sanitary napkin conveying device, the cylinder can drive the first transmission wheel 200 and the second transmission wheel 300 to move.

[0041] Electric push rod: can be used to push the first transmission wheel 200 and the second transmission wheel 300.

[0042] Through the combination of the transmission component 100 and the displacement assembly 400, the automatic conveying of the sanitary napkin conveying device can be realized, thereby improving efficiency and reducing manual operations.

[0043] The working principle of this utility model is as follows:

[0044] like Figure 4 As shown, in the process of removing the sanitary napkins, the lever 110 in the discharge station 140 needs to remain stationary, while the lever 110 outside the discharge station 140 needs to remain in a moving state, so that the sanitary napkins can continue to enter the conveying device; at this time, the displacement assembly 400 drives the first transmission wheel 200 and the second transmission wheel 300 to move, and the first transmission wheel 200 and the second transmission wheel 300 keep rotating at the same time, so that the lever 110 of the transmission component 100 at the discharge station 140 remains stationary, while the lever 110 at other positions of the transmission component 100 moves, so that the sanitary napkins can continue to enter the conveying device.

[0045] The actual workflow is as follows:

[0046] like Figure 1-5 As shown, 1) the levers 110 on the transmission component 100 are spaced apart so that sanitary napkins can be placed between the levers 110. The sanitary napkins are fed into the device through the feeding station 130. 2) The first transmission wheel 200 and the second transmission wheel 300 are connected to the transmission component 100 to drive the transmission component 100 to rotate. Figure 5As shown in part A of FIG, a preset number of sanitary napkins are pushed out of the conveyor, and the lever 110 of the transmission component 100 at the discharge station 140 remains stationary. To allow sanitary napkins to continue to enter the conveyor from the feed station 130, the displacement assembly 400 drives the first transmission wheel 200 and the second transmission wheel 300 to move to the right, and the first transmission wheel 200 and the second transmission wheel 300 continue to rotate. 3) As shown in FIG. Figure 5 As shown in part B of FIG, after a preset number of sanitary napkins are pushed out of the discharge station 140, the transmission assembly is moved to the rightmost end. At this time, the displacement assembly 400 drives the first transmission wheel 200 and the second transmission wheel 300 to move to the left. The first transmission wheel 200 and the second transmission wheel 300 keep rotating at the same time, so that the sanitary napkins can refill the discharge station 140. 4) As shown in FIG. Figure 5 As shown in part C, the discharge station 140 is filled with a preset number of sanitary napkins. As new sanitary napkins are fed into the feed station 130, the device continues to repeat the process of step 2) to achieve continuous delivery of sanitary napkins.

[0047] The sanitary napkin conveyor system relies on the coordinated operation of several key components: 1) Transmission component 100 and lever 110: These components support and convey sanitary napkins. 2) First and second transmission wheels 200 and 300: These components rotate the transmission component 100, enabling continuous conveyance of sanitary napkins. 3) Displacement assembly 400: These components control the lever 110's switching between stationary and mobile states at the discharge station 140, ensuring smooth removal of sanitary napkins.

[0048] In some embodiments, the transmission component 100 is a chain belt, and the first transmission wheel 200 and the second transmission wheel 300 are sprockets.

[0049] The chain belt consists of a series of interconnected chain links that can transmit power between two or more wheels. The advantages of the chain belt include high load capacity, durability and reliability. In the sanitary napkin conveying device, the chain belt can carry multiple shifting rods 110, each of which can be placed on a sanitary napkin. The sprocket is a wheel that engages with the chain belt and has a toothed design that can engage with the chain links on the chain belt. The main function of the sprocket is to drive the movement of the chain belt, thereby driving the shifting rods 110 and the conveyance of sanitary napkins. The design of the sprocket can ensure the stable operation of the chain belt and reduce slippage and wear. The combination of the chain belt and the sprocket can provide efficient power transmission because the engagement area between the chain belt and the sprocket is large, which can reduce slippage and energy loss.

[0050] In some embodiments, the displacement assembly 400 includes a moving base 410 and a first driving member 420 for driving the moving base 410 .

[0051] The movable base 410 is used to move the first transmission wheel 200 and the second transmission wheel 300. The design of the movable base 410 ensures that the transmission wheels can move along a predetermined path when needed, thereby controlling the delivery of sanitary napkins. The first drive member 420 is a component used to drive the movable base 410. It can be an electric, pneumatic, or hydraulic drive device. The function of the first drive member 420 is to provide power to move the movable base 410 along the guide rail or chute, thereby driving the first transmission wheel 200 and the second transmission wheel 300.

[0052] In some embodiments, the diameter of the first transmission wheel 200 is larger than that of the second transmission wheel 300 .

[0053] When the diameter of the first transmission wheel 200 is larger than that of the second transmission wheel 300, the transmission speed can be reduced. This is because in a chain or belt transmission, the speed of the chain or belt is the same on both wheels, so the smaller wheel will rotate faster.

[0054] In some embodiments, two ends of the movable base 410 are respectively connected to the first transmission wheel 200 and the second transmission wheel 300 .

[0055] In some embodiments, the movable seat 410 is further provided with an anti-tilt assembly 430 for preventing the sanitary napkin from tipping over.

[0056] When the displacement assembly 400 drives the first transmission wheel 200 and the second transmission wheel 300 to move, the anti-tilt assembly 430 is used to prevent the sanitary napkin from falling out of the sanitary napkin accommodating space 120 .

[0057] Furthermore, the anti-tilt assembly 430 includes an anti-tilt bar 440 , and the shape of the anti-tilt bar 440 matches the shape of the transmission component 100 .

[0058] The shape of the anti-tilt strip 440 needs to be closely matched with the shape of the transmission component 100 (such as a chain belt) to ensure the stability of the sanitary napkin during transportation and to prevent the sanitary napkin from rolling or tipping over during transportation.

[0059] In some embodiments, the first driving member 420 is a linear motor.

[0060] Linear motors offer advantages such as high starting thrust, high transmission stiffness, fast dynamic response, high positioning accuracy, and unlimited travel length. These characteristics make them ideal for sanitary napkin conveyors, particularly where rapid and precise control of the napkin's position and speed is required.

[0061] In some embodiments, the displacement assembly 400 includes a second driving member 450 connected to the second transmission wheel 300 , and the second driving member 450 is used to adjust the position of the second transmission wheel 300 .

[0062] During the assembly process of the first transmission wheel 200 , the second transmission wheel 300 and the transmission component 100 , the second driving member 450 can control the position of the second transmission wheel 300 , thereby controlling the tension of the transmission component 100 .

[0063] In some embodiments, the sanitary napkin conveying device further includes a first support base 500 for supporting the first transmission wheel 200 and a second support base 600 for supporting the second transmission wheel 300 . The first support base 500 and the second support base 600 are respectively connected to the displacement assembly 400 .

[0064] The first support base 500 and the second support base 600 are used to fix the first transmission wheel 200 and the second transmission wheel 300, so that the two ends of the movable base 410 can be connected to the first support base 500 and the second support base 600 respectively. By moving the first support base 500 and the second support base 600, the first transmission wheel 200 and the second transmission wheel 300 can be moved. The first transmission wheel 200 and the second transmission wheel 300 are respectively connected to a driving member, which is respectively fixed to the first support base 500 and the second support base 600.

[0065] The terms and words used in the above description and claims are not limited to their literal meanings, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, it should be clear to those skilled in the art that the above description of various embodiments of the present invention is provided for illustration only and is not intended to limit the present invention as defined in the appended claims and their equivalents.
