Detailed Description of the Embodiment

[0026] The following further describes the present invention in combination with the embodiments shown in all the attached Figures 1-5 figures, where Figure 5What is mainly shown is that the present invention is applied to a turntable assembly device. In addition, the present invention can also be applied to a linear transmission assembly device.

[0027] Embodiment 1

[0028] This embodiment discloses a double-row feeding device, which is a key transmission device applied to the automatic production of open-type composite cup lids. This device is used to convey, turn, and adjust the posture of the outer layer 011 of a cup lid with an open mouth and a height slightly greater than the diameter in a double-row synchronous manner, so that the outer layer 011 of the cup lid enters the subsequent pressing process in a state of uniform spacing and consistent opening direction. Figure 4 )in a double-row synchronous manner in an orderly manner, and the outer layer 011 of the cup lid enters the subsequent pressing process in a state of uniform spacing and consistent opening direction.

[0029] Refer to Figures 1-4 , this double-row feeding device mainly consists of a centrifugal power turntable 41, a connecting and supporting component 42, an orientation adjustment mechanism 43, and a shock-absorbing output component 44. The centrifugal power turntable 41 receives the outer layer 011 of the open-type cup lid input from the outside and outputs it in a single-row form from the discharge channel of the turntable by relying on centrifugal force; its rotational speed and turning diameter can be adjusted according to different product specifications to ensure stable conveyance. The connecting and supporting component 42 adopts a modular quick-disassembly structure, which is used to fix the centrifugal power turntable 41 on the main frame and has a certain buffering and shock-absorbing effect at the same time. The orientation adjustment mechanism 43 is accurately docked with the discharge channel, and the discharge direction of the outer layer 011 of the cup lid is adjusted through an actuator to ensure its correct alignment with the subsequent shock-absorbing output component 44; the control of the actuator adopts a closed-loop servo system, and the positioning accuracy ≤ 0.5 mm. The cloth bag container in the shock-absorbing output component 44 is made of imported wear-resistant material, and the surface is smooth; the container length and cloth bag specifications can be customized according to the product size. This device not only uses the cloth bag to slow down the falling speed of the cup lid, but also plays a certain isolation and protection role through the wrapping of the cloth bag, effectively reducing the surface abrasion of the outer layer.

[0030] To ensure that the outer layer 011 of the cup lid smoothly enters the orientation adjustment mechanism 43, a height interception mechanism 411 is provided in the conveying direction of the centrifugal power turntable 41. This mechanism can be a fixedly arranged railing, or it can be a railing and an interception block driven by a motor. The railing is fixedly arranged to play a height-limiting role; the interception block is installed on the driving screw rod, and its height position is controlled by a servo motor and can be adjusted according to the outer layer of the cup lid with different heights.

[0031] This elastic and controllable double interception method ensures that the outer layer 011 of cup lids of different specifications enters the directional adjustment mechanism 43 in a stable lying state. This is necessary to ensure the precise adjustment of the subsequent discharging direction. This structure adopts a modular design and can adapt to different products by changing the railings of different heights and adjusting the stroke of the interception block. The control parameters of the height interception mechanism are set through a menu on the human-machine interface, and rapid switching can be achieved without replacing mechanical components, meeting the flexibility requirements of the automated production line. This design fully embodies the control concept of mechatronics.

[0032] To clearly illustrate the structure and movement principle of the directional adjustment mechanism 43, refer to Figure 3 , the components of the directional adjustment mechanism 43 are shown exploded. The directional adjustment mechanism 43 includes: a discharge port 431 opened downward at the end of the discharge channel, a direction adjustment actuator 432 slidable perpendicular to the conveying direction at the discharge port 431, and a drive source 433 with the main body fixed at the discharge port 431 and the telescopic part connected to the discharge direction adjustment actuator 432. The dimension of the direction adjustment actuator perpendicular to the conveying direction is more than twice the width of the discharge channel. The direction adjustment actuator can completely close the discharge channel in the initial state. Inside the discharge direction adjustment actuator 432, there are an upper inclined surface 434, a lower inclined surface 435, and a split baffle group 436.

[0033] Among them, the inclined surface directions of the upper inclined surface 434 and the lower inclined surface 435 are the same as the conveying direction of the discharge channel. The length of the lower inclined surface 435 is set to accommodate only one outer layer 011 of the cup lid. When a string of outer layers 011 of cup lids is pushed by the power of the centrifugal power turntable 41 to fill the upper inclined surface 434 and the lower inclined surface 435, since only one outer layer 011 of the cup lid can be placed on the upper inclined surface 434, the second outer layer 011 of the cup lid is placed on the upper inclined surface 434. When the power of the centrifugal power turntable 41 is removed, the second outer layer 011 of the cup lid will slide backward to the bottom of the slope under the action of the inclined surface, and there will be a gap between the first and second outer layers 011 of the cup lid. This gap is set to correspond to the position of the die in the next process because the double-row dies are arranged side by side and there must be a gap.

[0034] Among them, the split baffle group 436 is arranged side by side with the upper inclined surface 434 and the lower inclined surface 435. The split baffle group 436 includes two sets of split baffles 361 that can be opened and closed, which are usually in a closed state. Each set is provided with a tapered hole 437, and the upper and lower hole diameters are respectively larger and smaller than the maximum / minimum diameter of the outer layer of the cup lid. The included angle of the two inclined surfaces and the parameters of the tapered hole can be adjusted according to the product. The opening and closing of the split baffle 361 are driven by setting a motor.

[0035] In order to prevent the outer layer of the cup cover ranked third and behind from touching the outer layer of the cup cover ranked second, a temporary positioning cylinder 5 is arranged in the discharge channel to temporarily restrict the outer layer of the cup cover ranked third by means of resistance or obstruction.

[0036] When the directional adjustment mechanism 43 is working, the driving source 433 drives the direction adjustment actuator 432 to move, and the two conical holes 437 gradually move to the bottom of the corresponding cup cover outer layer 011. Since the center of gravity of the bottom surface of the cup cover outer layer 011 is larger, the bottom surface will automatically open downward and face upward under the action of the inclination of the conical surface. When the two sets of split baffles 361 are opened synchronously, the two cup cover outer layers 011 will naturally fall down into the shock-absorbing output component 44 with the opening facing upward.

[0037] To improve synchronization, the opening of the split baffle set 436 can be driven by multiple motors with transmission matching devices. In addition, a limit switch can be added to the split baffle set 436 to accurately control its opening and closing angle.

[0038] The shock-absorbing output component 44 has a rigid frame 441 on the outside and a cloth bag on the inside. The material and thickness of the cloth bag can also be optimized according to the product characteristics.

[0039] In addition, in order to increase the applicability of the same set of equipment, a position baffle 6 is detachably arranged on the lower inclined surface 435, so that during the conveying stage, only one cup cover outer layer 011 can be accommodated on the lower inclined surface 435 to ensure that the second cup cover outer layer 011 falls on the upper inclined surface 434. When the split baffle group 436 is switched to enter under the two cup cover outer layers 011, due to the setting of the conical hole 437, the two cup cover outer layers 011 will automatically fall in and will not cause any impact.

[0040] Furthermore, in order to better separate the first and second cup cover outer layers 011, a barrier block 7 is provided between the two sets of split baffles 361 to serve as a barrier during switching.
