[0027] The feeding table 1 comprises a cross frame 12 supporting a rotatable turntable 11, the outer periphery of the turntable 11 is surrounded by a fixed guide rail 16, the end of the guide rail 16 forms a discharge port 17 with a notch, the discharge port 17 extends inwardly to a limit plate 15, and a spiral channel is formed between the limit plate 15 and the guide rail 16, which can rotate the wet paper towel cover to be printed along the guide rail 16 to the discharge port 17 clockwise along with the turntable 11.
[0028] Please refer to the drawings in the description Figures 1-3 The first embodiment of the wet paper towel cover printing rotary feeding table 1 is provided, and in the embodiment, the rotary feeding table 1 mainly comprises a feeding ladder 2 and a feeding table 1. The feeding ladder 2 is obliquely supported on the feeding end of the feeding table 1, and comprises a conveying frame 21 carrying an oblique square frame 24. The lower end of the square frame 24 is clamped with a feeding motor 23, the power conveying end of the feeding motor 23 is coupled with a feeding roller 25 through a shaft coupling, the outer periphery of the feeding roller 25 is sleeved with an elastic feeding belt 251, and the elastic feeding belt 251 is arranged obliquely along both ends of the square frame 24. The top of the feeding belt 251 is spanned with a box-shaped hollow standby hopper 22, the bottom of the standby hopper 22 is in contact with the feeding belt 251, and the inside contains the wet paper towel cover to be conveyed. When the feeding motor 23 is started, the feeding belt 251 rolls clockwise, and drives the wet paper towel cover in the standby hopper 22 to be conveyed along the oblique path to the feeding table 1.
[0029] Preferably, in order to improve the conveying stability of the wet paper towel cover, the bottom surface of the above-mentioned box-shaped hollow standby hopper 22 is designed as an arc-shaped recess structure in contact with the feeding belt 251, and the inclination angle is consistent with the inclination angle of the oblique square frame 24 of the feeding ladder 2. At the same time, the elastic feeding belt 251 is made of silica gel material, and the surface is uniformly distributed with anti-skid convex patterns to increase the friction force with the wet paper towel cover and prevent slipping during conveying.
[0030] The feeding table 1 comprises a cross frame 12 supporting a rotatable rotating disc 11, the rotating disc 11 is connected with the driving mechanism of the cross frame 12 through a central shaft and can rotate clockwise around the central axis. The outer periphery of the rotating disc 11 is surrounded by a fixed guide rail 16, and the end of the guide rail 16 forms a discharge port 17 with a notch. The inner side of the discharge port 17 extends a limiting plate 15, and the limiting plate 15 and the guide rail 16 form a spiral channel. When the rotating disc 11 rotates, the wet tissue cover is moved along the guide rail 16 under the action of centrifugal force and is orderly transferred to the discharge port 17 through the spiral channel.
[0031] Further, in order to optimize the positioning accuracy of the wet tissue cover, the bending angle of the limiting plate 15 in the embodiment can be adjusted, and the limiting plate 15 is fixed on the outer periphery of the rotating disc 11 by bolts, so as to adapt to wet tissue covers of different sizes and quantities. At the same time, the width of the spiral channel gradually decreases from the discharge port 17 to the center of the rotating disc 11, so as to ensure that the wet tissue cover is automatically aligned during the transfer process and avoids deviation.
[0032] Embodiment two
[0033] In combination Figures 1-3 Based on the above-mentioned embodiments, the embodiment further provides the following contents:
[0034] In the embodiment, the upper end of the limiting plate 15 is clamped with a pressing block 112 connected with the guide rail 16 and can slide to adjust the distance between the limiting plate 15 and the guide rail 16, so as to instantaneously change the delivery amount of the wet tissue cover per unit time.
[0035] The upper end of the guide rail 16 is longitudinally crossed with a rigid support fixed bending sliding block 111, and the lower end is clamped with a buffer plate 14, which can change the bending degree of the buffer plate 14 by sliding left and right with the bending sliding block 111, so as to store the wet tissue cover delivered by the feeding ladder 2 inside the limiting plate 15 and avoid the wet tissue cover from rushing out of the rotating disc 11.
[0036] The outer periphery of the feeding belt 251 is vertically provided with an elastic partition plate, which can be conveyed by rolling with the feeding belt 251, and is used for the quantitative delivery of the feeding ladder 2.
[0037] Please refer to the drawings in the description Figures 1-3 The second embodiment of the rotating feeding table 1 for wet tissue cover printing is provided, and in the embodiment, the upper end of the limiting plate 15 is clamped with a pressing block 112, the pressing block 112 is connected with the top of the guide rail 16 through bolts and can slide in the longitudinal sliding groove of the guide rail 16, so as to adjust the distance between the limiting plate 15 and the guide rail 16. By adjusting the position of the pressing block 112, the passing gap of the wet tissue cover in the spiral channel can be changed in real time, and the accurate control of the delivery amount per unit time can be realized.
[0038] Preferably, in order to improve the stability of the wet tissue cover transfer, the upper end of the guide rail 16 is longitudinally provided with a rigid support bending slider 111, which is fixed on the top of the guide rail 16 by clamping and has an integral buffer plate 14 extending above the turntable 11. The buffer plate 14 is made of elastic rubber material and can change the bending angle and contact force by sliding the bending slider 111 left and right. When the wet tissue cover conveyed by the feeding ladder 2 enters the area of the turntable 11, the buffer plate 14 absorbs the impact force by elastic deformation and guides the wet tissue cover to the storage area inside the limiting plate 15, avoiding the wet tissue cover from being thrown out of the turntable 11 due to excessive centrifugal force.
[0039] Further, in order to optimize the quantitative conveying function of the feeding ladder 2, a plurality of elastic partitions are uniformly arranged on the outer periphery of the feeding belt 251. The elastic partitions are made of silicone material and have a height of 1 / 3 of the width of the feeding belt 251, and their spacing distance can be set according to the size of the wet tissue cover. When the feeding belt 251 rolls clockwise, the elastic partitions move with the belt body, forming independent and separate conveying units, each unit accommodating only a certain number of wet tissue covers, thereby realizing quantitative conveying of the wet tissue covers and avoiding overlapping and deviation of multiple wet tissue covers.
[0040] Preferably, in order to enhance the adjustment flexibility of the bending slider 111, lock knobs are arranged on both sides of the bending slider 111. The fixed state between the slider and the guide rail 16 can be released by rotating the knob, and then the slider can be moved along the sliding groove of the guide rail 16. After adjusting the position of the slider, the knob is locked again to ensure that the bending force of the buffer plate 14 matches the transfer speed of the wet tissue cover, further improving the positioning accuracy.
[0041] Further, in the embodiment, the top of the elastic partition is designed as an arc structure, and the front end is aligned with the outlet of the feeding ladder 2. When the wet tissue cover slides from the material hopper 22 into the feeding belt 251, the arc-shaped top of the elastic partition can guide the wet tissue cover to enter the conveying unit smoothly, avoiding jamming and collision damage. In addition, the root of the elastic partition is integrally formed with the feeding belt 251 by hot pressing process, ensuring that it is not easy to fall off and deform during long-term rolling.
[0042] Embodiment Three
[0043] In combination Figures 3-4 Based on the above embodiments, the present embodiment further provides the following contents:
[0044] In the present embodiment, the fork 12 is provided with a rotating motor 13 connected with a rotating sprocket 131 arranged at the bottom of the turntable 11, for long-term use of the turntable 11.
[0045] The upper end of the feeding belt 251 is provided with a square limiting channel 26 between the rotating disc 11, which can receive the wet tissue cover transported by the feeding belt 251 to the rotating disc 11, and is used for accurate transportation of the wet tissue cover.
[0046] Please refer to the description of the drawings Figures 3-4 The utility model provides a third embodiment of wet tissue cover printing rotation feeding platform 1, in this embodiment, cross frame 12 is provided with rotating motor 13, the output shaft of rotating motor 13 is connected with the rotation sprocket 131 of the bottom shaft of rotating disc 11 through the shaft coupling, the gear shape of rotation sprocket 131 is engaged with the annular tooth groove of the bottom of rotating disc 11, when rotating motor 13 starts, power is transmitted to rotating disc 11 through the sprocket, drives its clockwise uniform rotation around the central shaft of cross frame 12, thereby realizing the long -term stable operation of rotating disc 11.
[0047] Preferably, in order to improve the transportation accuracy of the wet tissue cover from the feeding ladder 2 to the rotating disc 11, the upper end of the feeding belt 251 is provided with a square limiting channel 26 between the feeding end of the rotating disc 11. The limiting channel 26 is welded by four stainless steel plates, the inner cavity width thereof is matched with the size of the wet tissue cover, the bottom thereof is connected with the end of the feeding belt 251, and the top thereof extends to the entrance of the guide column 16 of the rotating disc 11. When the wet tissue cover moves to the limiting channel 26 along with the feeding belt 251, the two sides and the top thereof are limited by the inner wall of the channel, and can only slide into the spiral channel of the rotating disc 11 along the preset path, so that deviation and misplacement in the transportation process are avoided.
[0048] Further, in the embodiment, the surface of the rotation sprocket 131 is coated with a wear-resistant coating, and the engagement gap between the sprocket and the tooth groove of the rotating disc 11 is adjusted by adjusting screws for fine adjustment, so as to ensure the stability of power transmission. At the same time, the inner wall of the limiting channel 26 is attached with a high-molecular material with low friction coefficient, so as to reduce the resistance when the wet tissue cover slides, and further improve the transportation efficiency.
[0049] The working principle and use process of the utility model are as follows:
[0050] 1. Equipment preparation and material loading: the operator pours the wet tissue cover to be printed into the box-shaped material hopper 22 of the feeding ladder 2, and ensures that all the wet tissue cover is poured in. Then, the coupling state of the elastic feeding belt 251 and the feeding roller 25 is checked, and it is confirmed that there is no foreign matter blocking the contact surface between the bottom of the material hopper 22 and the feeding belt 251. At the same time, the distance between the limiting plate 15 and the guide column 16 is adjusted, the lower pressing block 112 at the upper end of the limiting plate 15 is slid, and the transportation amount of the wet tissue cover per unit time is set.
[0051] 2, start the feeding system: start the feeding motor 23, drive the feeding roller 25 to drive the elastic feeding belt 251 to roll clockwise. The wet wipes in the standby hopper 22 slide to the surface of the feeding belt 251 under the action of gravity, and are separated into independent units by the elastic partition, and are transported to the feeding table 1 direction along the inclined square frame 24 one by one. The square limiting channel 26 at the end of the feeding belt 251 limits the wet wipes cover in the preset path, ensuring that it slides into the turntable 11 accurately.
[0052] 3, the rotation of the turntable 11 and the transfer of the wet wipes cover: start the rotating motor 13 in the cross shaft 12, drive the turntable 11 to rotate clockwise at a constant speed through the rotating sprocket 131. The wet wipes cover moves along the guide rail 16 under the action of centrifugal force after entering the spiral channel of the turntable 11 from the limiting channel 26. The bending slide block 111 at the upper end of the guide rail 16 and the buffer plate 14 absorb the impact force of the wet wipes cover through elastic deformation, and guide it to the storage area inside the limiting plate 15, avoiding the wet wipes cover from rushing out of the turntable 11 due to excessive speed.
[0053] 4, printing feeding and dynamic adjustment: during the continuous rotation of the turntable 11, the wet wipes cover moves along the spiral channel to the discharge port 17, and finally is discharged one by one through the discharge port 17 of the gap to the printing station. If the feeding rhythm needs to be adjusted, the operator can slide the lower block 112 of the limiting plate 15 in real time to change the gap width of the spiral channel to adapt to different size or printing speed requirements.
[0054] 5, end operation and maintenance: after completing the printing task, turn off the feeding motor 23 and the rotating motor 13 in turn. Clean the residual wet wipes cover in the spiral channel of the turntable 11 and the standby hopper 22, check the wear condition of the elastic partition, the feeding belt 251 and the buffer plate 14, and replace the parts if necessary. When long-term inactivity, add lubricant to the rotating sprocket 131 and the feeding roller 25 to ensure the running stability of the equipment when it is started again.
[0055] The above only describes the preferred embodiments of the present application, and does not limit the present application.
